DIY 6 ch arduino nano ESC, with some vital features:
6channels bidirectional (3A per channel)
CPPM receiver (cheap and small 3 wires)
Auto Power Off
Battery level indicator
"Flying" power button
Extra servo Plug

PCB from JLCPCB (I paid 9 euro 5 pieces shipped):
https://jlcpcb.com/

Motor control IC is a TLE94112EL

Source code gerber and schematic are:

Sorry, It is not a github project, just a repository, I'm not good on github yet

this first Version is configured as:
Vin 23 Cells lipo (low battery is set now for 2 cells)
Max current:
4ch 3A
1Ch 4A
1CH 2A

Next version (if I will continue) will have probably all the channels 3A and with some jumpers you can have 2x4A and some 2x2A channels

feel free to suggest improvements
