Currently, theses are the problems with this PCB :
The 5V supply is connected to BlackPill's VBat instead of the 5V supply of the board. The VBat pins are for powering the board in deep sleep (only the RTC quartz and the RAM will be powered).
Micromatch connectors are used to connect with the H-bridges while they are difficult to set up and to debug.
It would be great to have a "Hardfault" Led available on some pin to toggle upon hardfault.
It would be great to have a "Transmission" Led available on some pin to toggle upon communication initialization.
