Hi @Vinny ,
I have couple questions on FCv2 hardware, thank you!
- what is the purpose of STM32 UART7 through level shifters (74LVCH2T45)? both VCCA and VCCB are same 3.3V domain?
- J2 - where is VPP_STM connect to and what is the function?
- J5 - why there is no level shifter on UART5?
- J13 - Is that PM monitoring really need for FC? Can I just use a adc pin to monitor battery voltage through the divided resistors?
- RGB1 LEDs are controlled by GPO PE3/4/5, please confirm which pin for witch color.
Thanks,
Daniel
