serial-out contains mbed code for producing serial out, using PA_9 for TX, and PA_10 for RX
The USB can be used for serial communication via Serial in the Arduino IDE. See
stm32-hello-arduino. A CP102 chip is used (I believe) to
perform the communication.
The pins used are PA11 (USB-) and PA12 (USB+).
- esp32-proxy - forwards serial communications (e.g. from stm32). Use pins labelled RX2 and TX2 on WROOM
