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.
@Will Have you considered purchasing another one? They are not expensive, and might be much more worth it than your time lost to fight a non-functional USB on the MCU.
Food for thought...
Sadly, I am not one of the SW experts in our team... just HW.
Tag me anytime you have HW related questions!
I was able to use the v1.13.2-0.1.1 file with mission planner, it connected but said update was not required. I will keep an eye out for the v1.13.2-0.1.2 drop. Looking into my compass setup, its a new release from MRO, could be an issue there
