A board to connect a single host to multiple dev/eval boards, each with:
- Power over USB
- USB (shared with above?) for Fastboot communication
- Serial (RS-232)
Only one board can be active at a time. The current board can be selected using a [switch/microcontroller]? and is displayed on a [screen/LEDs]?.
Currently, the chip select output is handled by a 3 bit address (3 slide-switches) and submitted using a single toggle switch.
The idea is that this board gives a clean interface between my host PC and full rack of microcontrollers/SoMs without fiddling with wires.
