Fredrik, do we have an unused UART in STM32? I was thinking, maybe we 
can add a 4-pin header (TX, RX, 3V3, GND) to Alpha. Peter can then 
design simple extension board with little ARM and USB connector. Once 
the board and protocol firmware for the little ARM are ready, we will be 
able to throw away FTDIs and just borrow Peter's design. What do you think?
