No doubt the power of digital system. Only 100mW and the quality never dropped.

My DiY Goggle Finally is READY!
The RubyFPV is really astounding!!! Very stable and solid. I had migrate my Eachine ev100 into a custom designed 3d case, putting the Pi Zero 2W, USB hub module, 5 DCDC regulator, bl-m8812eu2 WiFi module card and etc into one single case. I had chosen yellow because it looks like minion.

Parallel Charging Board (2S x 6)
Previously had designed and not working great as not added any fuse and polyfuses between the balancer lead and battery. This round I had made it to protect some serious shortcircuits that we never thought it will happened. Safety first.
What I had done this round is added the poly fuses to all the balancer leads. This will reset after it breaks off. Just cool it down and the fuse will be back to normal. For the battery leads, all added a fuse holder with fuse. This will allows the fuse to be easily changed if ever shortcircuit is happened.
Why 2S? Well, all my designed for my current quad is using only 2S and I am limiting to 2S for small quads that are around 3 inches frame only. Also all the motors I am currently using are max at 2S power. I prefer it to be small and fun.
The Schematic as below:
Have a nice day!
