Finally came to an end where I need to redesign the schematic again for lesser components and trying to get power source from FC rather from itself. The whole idea is to cut costs and able to build it easily. Below is the diagram currently I am working on and going to test out the firmware on BLHELI_s with the version O_H_5 but with some minor modification on the code. I had accidentally swapped the pins at the MOSFETs side. Lets see how it goes once the board is back from JLCPCB. ...

Finally added a new repository server to my site. This will store all my source codes for the FPV related projects here. Freely shared to everyone to rebuild it. I will constantly update it. Stay tune. https://git.bertfpv.com/explore/repos

So far I had finished assembling the parts but still awaiting for some major parts arrival to confirm all the schematic are working before migrating to the All-In-One board. Front PCB: Back PCB: Is my first time working on 0402 size components. Still need to clean up those small dirty residuals from the paste. Also noticed that some of the parts still empty as I am still awaiting for the arrival of the components. That is the main buck-boost converter for this ESC project. As this ESC specification is as below: i. Operation Voltage: 2.5v ~ 4.2v ii. Operation Current: Maximum at 5A iii. BLHELI firmware compatible ...
