  • For anyone else thinking about flow control, it looks like AT_UART_DEF is the command you need to turn on hardware flow control in the AT firmware, and then it'll use the MTCK pin (GPIO13) for CTS. I'll make sure I tie that up to some IO in the new Espruino board just in case.

    Yes, the board will have a fuse in it - while there is a diode it's only there to stop voltage flowing back into USB, so it won't protect against reverse voltage I'm afraid.

    The ESP12 module is actually pretty tight on the back - putting the STM32 on top means there's enough space to (finally!) have pin markings where they can be seen - which I think is probably better than being slightly more SMD mountable :)
