[{"content":"\nMost FPV pilots head to the field carrying a small mountain of gear: a radio in one hand, goggles or a separate screen in the other, plus a bag of receivers, antennas, and cables tying it all together. It works — but it has always bugged me. Why are the two things I stare at most, the controls and the video feed, living in two separate boxes?\nSo I stopped asking and started building. Meet the BERT RC Controller — a single handheld unit that fuses a fully custom ESP32-based radio with a long-range RubyFPV digital video ground station. One device. Two brains. Everything I need to fly, in my own design, down to the last toggle switch.\nHere\u0026rsquo;s a first look at the build.\nThe control heart: ESP32 with custom RC firmware At the core of the radio side is an ESP32, running firmware I\u0026rsquo;m writing from scratch rather than flashing something off the shelf. Going custom means I\u0026rsquo;m not boxed in by someone else\u0026rsquo;s menu structure, channel limits, or mixing logic — I decide exactly how every input maps to every output, how the UI behaves, and how the link is configured.\nThe ESP32 is a fantastic brain for this: dual-core, plenty of headroom for reading the sticks and switches in real time while simultaneously driving the display and talking to the radio module, all with Wi-Fi and Bluetooth sitting in reserve for future features. This is the part of the project I\u0026rsquo;m most excited to document, because the firmware is where a pile of parts turns into an actual transmitter.\nContactless precision: dual Hall-effect gimbals The two sticks are Hall-effect sensor gimbals, and if you\u0026rsquo;ve only ever flown radios with traditional potentiometer gimbals, this is the upgrade you feel immediately.\nInstead of a wiper physically scraping across a resistive track, Hall gimbals read stick position magnetically — nothing touches, so nothing wears out. That translates to smoother, more linear control, no scratchy center detents developing over time, and far less drift after months of hard flying. For a controller I plan to actually depend on, contactless sticks were non-negotiable.\nSwitches, buttons, and channels There are ten toggle switches in total — six on the front face flanking the gimbals, plus another four mounted along the top edge of the controller where my fingers naturally rest. On top of those, a tidy 2×3 array of chunky orange momentary buttons sits in the lower-left of the faceplate. Together that\u0026rsquo;s a genuinely generous spread of physical inputs to assign — arm/disarm, flight modes, buzzer, VTX settings, camera triggers, you name it.\nMapping all of that in firmware is half the fun. Because the logic is mine, a single switch can do something simple like a 2-position channel, or something clever like cycling through a menu — and with ten toggles plus six buttons, I\u0026rsquo;m not going to run out of channels any time soon.\nThe RF link: ExpressLRS for serious range Sticks and switches mean nothing if the signal can\u0026rsquo;t reach the aircraft, so the radio talks to the world through an ELRS (ExpressLRS) module. ELRS has earned its reputation for a reason — extremely low latency, rock-solid link recovery, and the kind of long range that lets you push out confidently. The ESP32 feeds it the channel data, and ELRS handles getting that data to the model cleanly and reliably.\nEyes-on telemetry: the 2.25\u0026quot; TFT Right on the face of the controller sits a small 2.25-inch full-colour TFT display. This is the radio\u0026rsquo;s at-a-glance dashboard — link quality, battery voltage, active model, switch states, telemetry coming back from the craft, and whatever else I decide matters in the moment. No phone, no companion app, no guessing. The information lives where my eyes already are.\nThe other brain: a RubyFPV HD ground station Here\u0026rsquo;s where the BERT RC Controller stops being \u0026ldquo;just a radio.\u0026rdquo; That large screen dominating the centre of the unit is a serious piece of glass, and behind it is a completely separate video system running RubyFPV on a Raspberry Pi 4B (2GB).\nFor the video link itself, I\u0026rsquo;m running two BL-M8812EU2 Wi-Fi modules. RubyFPV uses these in a way that gives you genuinely high-quality, long-range digital video — diversity reception across both adapters means a more robust feed and fewer dropouts as you get further out or fly behind obstacles. The result is an HD picture that holds up where analog would have turned to static.\nAnd that centre screen is no afterthought. It\u0026rsquo;s an original Tianma IPS panel — the same native touch assembly used in handhelds like the ROG Ally and MSI Claw — so the FPV feed gets a display worthy of it:\nSpec Detail Size 7-inch IPS Resolution 1920 × 1080p (314 ppi) Refresh rate 120 Hz Response time 7 ms Brightness 500 nits Contrast ratio 1000:1 Colour gamut 100% sRGB Aspect ratio 16:9 Touch 10-point capacitive (original Tianma assembly) Connectivity Single-cable USB-C, mini-HDMI Dimensions ~167 × 109 × 9 mm Weight 194 g Shell CNC-machined aluminium alloy Extras Built-in speakers, volume/brightness scroll-wheel keys A 120 Hz, 1080p, 500-nit panel is overkill in the best possible way — bright enough to actually see in sunlight, fast enough that the feed feels live, and sharp enough to read OSD details at a glance.\nThe shell All of it lives inside a two-tone 3D-printed enclosure — crisp white faceplate, black body and grips, with \u0026ldquo;BERT RC CONTROLLER\u0026rdquo; embossed proudly across the top. Designing the case is its own rabbit hole: gimbal mounts, switch cut-outs, the screen surround, ventilation, and grips that actually feel good after a long session. Seeing the printed shell come together with the electronics dropping into place is one of the most satisfying moments of any build.\nWhat\u0026rsquo;s next Right now you\u0026rsquo;re looking at the hardware taking shape. The real work — wiring it all up, writing the ESP32 firmware, getting the gimbals calibrated, bringing the RubyFPV ground station online, and tuning the whole thing into a controller I\u0026rsquo;d actually trust over my models — is just beginning.\nI\u0026rsquo;ll be documenting every step: the schematics, the firmware, the 3D files, the wins and the inevitable head-scratchers. If you\u0026rsquo;ve ever wanted to build your own radio instead of buying one off the shelf, this series is for you.\nStay tuned for the next post, where the build officially begins. 🚁\n","permalink":"https://www.bertfpv.com/building-the-bert-rc-controller-a-diy-esp32-radio-with-a-built-in-rubyfpv-hd-ground-station/","summary":"\u003cp\u003e\u003cimg loading=\"lazy\" src=\"/wp-content/uploads/2026/06/20260624_083904-1024x473.jpg\"\u003e\u003c/p\u003e\n\u003cp\u003eMost FPV pilots head to the field carrying a small mountain of gear: a radio in one hand, goggles or a separate screen in the other, plus a bag of receivers, antennas, and cables tying it all together.

The problem was during 3.6v and above the output will be getting higher linearly. So I had added a diode with a 0.6v forward drop voltage. This enables it to have a stable output at 3.3v.\nThis board design is only meant for 1S. Meaning operating voltage is in between 2.0v ~ 4.2v. Higher than that you need to modify the buckbooster part into a 3.3v LDO as well as the 5v power line to a 5V LDO. I modified this from OMNIBUSF4PRO to my custom made version. I removed SDCard as the blackbox to save more space for the All-In-One board.\nFor the USB port, I am not supplying the 5V to the board. It needs to be power up from the 1S battery. I dont want it to overload my laptop 5V to it or maybe accidentally shorted the board cause the laptop 5V logic all burned off. That is why I designed it not to supply to the board but needs to power up with the battery or some power supply regulator to the board before the USB port is recognized by the laptop or PC.\nFor the ESC part, is designed to be running on 1S. The MOSFETS are running at 5A maximum at continuous and pulse drain at 12A. Due to the ESC I had flashed with BlueJay, it should be able to handle a bit more then 5A. The trigger level (Vgs) of the MOSFET is very low, there isn\u0026rsquo;t need any MOSFET drivers. The only thing, we need to invert the output from one of the line to drive the P-MOSFET. If intended to driver higher current, try to find another type of MOSFET and replace it. The ESC design also can be used those single MOSFET rather 2-in-1 MOSFET. It will be bigger but reliability wise should be better. When designing a higher voltage ESC, meaning more than 1S, you will need higher current rating of the MOSFET and may need to add a driver or custom transistor to drive the MOSFET. I will be working on higher \u0026ldquo;S\u0026rdquo; ESC in near future. These designs are came from tinyPEPPER - https://fishpepper.de/projects/tinypepper/ with some modifications done to the schematic where it enables it to run at a very low voltage to provides stable 3.3v to the EFM8BB21F16G and is sharing with the main board FC\u0026rsquo;s 3.3v powerline. This will save some costs of making this FC. One 3.3v buckbooster that powers up the FC, Gyro, Baro, VTX, Cam, ESC and etc. It will not draw more than 1A as I had tested so far. The VTX is powered up by another 5V buckbooster power line. So is totally not affecting each other.\nFor the FC firmware, I am using INAV 3.0.1. I am a INAV fans. For betaflight it will work too but need to changed to OMNIBUSF4 board for the firmware.\nInitially, the ESC\u0026rsquo;s EFM8BB21F16G are blank. You need to flash in the firmware using C2CK and C2D pins before you can flash the ESC firmware over serial passthrough method. Once if flashed, all ESCs will be appeared in the INAV configurator. You even can use the BLHeli or BlueJay configurator to set your preferred settings. If you need to know how to flash in the ESC firmware, you can read from here -\u0026gt; https://www.bertfpv.com/how-to-flash-blheli_s-firmware-to-efm8bb21f16g/. You will be able to have a full control of your hardware and without fear of broken it again.\nI will include the gerber file on the next version. For this version, I still need to fix the distance between the pads and the SMD components. It needs a very steady hand to solder the wires on it. So I am going to built version 2.0 very soon.\nSponser this project:\nhttps://www.buymeacoffee.com/bertfpv\nBelow is the schematic diagram for this All-In-One flight controller I had built.

I had bought a broken Futaba Radio Controller and stripped off all the components inside the case and just left only the toggle switches and the gimbals. I linked them to my arduino nano for the first version that I have. I was using a very long antenna to maximize the 2.4G range.\nVersion 1.0 - Running on Arduino, without removing the original display and with a long antenna.\nLater on, found that need a display to monitor the status and all the readings and decided to strip away the display and become a fully own custom version with display. Of course the case still a normal RC Transmitter case.\nVersion 1.1 - Upgraded with Buzzer and Display (OLED)\nHad been using this a while and keep trying to learn flying at that time. Didn\u0026rsquo;t noticed about the precision I need that time. This Futaba gimbals are analog and the readings are about +-10% accuracy. Well, I was flying stable mode at that time and was enough for me.\nThis is the 1st quad I had build and flew with the barebone arduino with breadboard on it. Everything is hard wired. Wrongly match ESC with Motors. Kept burning ESC halfway in the middle of flying the quad until one day finally got it right. Big quads must use LOW KV, small quads must use HIGH KV. This will be another topic of it.\nSo once I am getting used to what I need, I had built a few racing quads with my own custom receiver and custom RC Transmitter. Until I had reached my limits and found out that actually I need something that are more precise in gimbal readings and faster processing microcontroller. I had upgrade from ATMEGA328 to STM32F1 chipset. But this also not for pretty long because I cant get what I need and the flexibility I wanted. Within the same year, I had upgrade to another version where the Radio Control Transmitter is totally 3D printed with FrSky M10 Gimbal Hall Effect sensor, ESP32, EByte E01-2G4M27D (Replica of nRF24L01) with 5km range and custom charging and 4 toggle switches. It was a development stage and the look of it like frankenstein because everything is opened.\nThe Frankenstein version.\nIt comes with dual OLED, for the fun of it and is running on ESP32 with BLE, WiFi and lots of computation power. I love this so much. The problem of this was a bit clunky and a bit opened. Very vulnerable from water that splashed in if is raining and so on. Well, I finally ditched off everything migrated to a better version and better designed of the Radio Controller Transmitter.\nI designed this from scratch using OpenSCAD.\nAnd the out come\u0026hellip;\u0026hellip;\nThis is the latest version I have for now\nYeah, A little bit difference but almost there. I used:\n9 Push switches 10x15mm ESP32 16MB 2 x FrSky M10 Gimbal Hall Effect Sensor 1 x 0.96\u0026quot; OLED 30AWG silicon wires 1 x 18650 Battery Holder Custom design PCB and fabricated by JLCPCB 1 x EByte E01-2G4M27D Lots of SMD components (Look at the schematic) I had perfected the menu display without using any buttons but using the gimbal to scroll through the items. Trying to save some I/O pins for the switches so I am having more channels to play with. I used to have a charger module built in with this but for this version I had removed it for the simplicity. Just charge the 18650 cell with a proper charger module and swap another piece if is low power.\nThe schematics:\nSchematic_NaMiTX-v1.1_2021-07-11Download\nWARNING: Still in progress of development. The current meter is not usable for this as the current draw was less than 1A. The designed was for quads that is draining \u0026gt; 1A. I will need to fix that and also the buzzer driver, I had put the MOSFET wrongly. I will need to change that in future. For now I had temporary disabled the buzzer. As well as the power latch section, I cant wait for the components arrival. I had altered to an ordinary power regulator module which stabilized the voltage from 4.2v -\u0026gt; 3.3v. The minimum operating voltage is about 3.5v as I had measured.\nThe PCB Layout\nI will share the gerber later once I had perfected the issues.\nInitial plan was thinking to have it run under 2.5v but the chip havent arrive until now.

In future, I will try to convert it to Linux when I have the time.\nFirst get an Arduino Nano as the Interface module between BLHeliSuite and the Custom ESC. You will need to flash it with the provided HEX to the Arduino Nano.\nThe above image indicates the PINS to be connected to the Custom ESC for the 1st initial firmware loading. Load up the BLHeliSuite and select the serial port that is connected to the machine also select the Arduino 4way-interface\nNext load up the Choose firmware dialog box.\nSelect the 4wArduino_Nano__16_PD3PD2v20005.hex and click Open then flash the firmware into the Arduino Nano. This you will have the Arduino Nano to be the Interface medium between the BLHeliSuite and the Custom ESC.\nBelow is the image on how to connect the wires to the custom ESC from the Arduino interface:\nTo load the initial firmware, you will need to pick the SILABS CS(4way-if) under the SELECT ATMEL/SILABS interface menu.\nSelect the right COM port and start to click on the CONNECT button and follow by the \u0026ldquo;Read Setup\u0026rdquo; button. If everything working, you will see something similar as below image.\nFrom here, you can start to load up different firmware to experiment with the custom firmware to the custom ESC. Bear in mind, you may get smokes out of the MOSFETs. You will need to limit the current and voltage do to the settings and testings.\nYou can even swap the pins in the code and compile into HEX and upload to the ESC using this BLHELISuite. Of course, once this first initial version flashed in, you can start to use your FlightController to do a pass-thru for the firmware upgrades, settings and everything. I was testing on INAV 3.0 and it works great! Hope these will help some new comers whom wish to build and flash their own first firmware into a blank EFM8BB21F16G.\nI had included the download link for users who interested to download and use it.

All my info on building the quad including the electronic boards and everything. I hope this will keep on going as I had already on this hobby for more than 5 years of Research and Development.\nPreviously, I had a site known as EchoWii which no longer available. EchoWii was only for FC that builds on-top on MultiWii. I had done lots of improvement on it and started to moved on and building receivers and radio controllers. So after a while moved on to FPV flying with acro mode. Then slowly learns about INAV, betaflight and so on.
