Is there a plan to support a UART class which could be used for multiple UARTs on the microbit V1 or V2? As I understand it there's only a, microbit.uart, a single UART instance used for the serial console over USB and this can be used on other pins but the serial console is then lost. It would also be useful if it could be configured for low output when no data is being transmitted, i.e. the invert functionality of general MicroPython's UART.

If the microbit.uart is re-purposed what happens to print statements in a program or library potentially and uncaught exceptions from the interpreter?

I wanted this for communication between a pair or more of micro:bits. For now I am using radio successfully. If there are any other good options would be great to hear about this.
