But what I need is actually the reverse of MicroMod:
- a standard carrier base with USB, uC (Teensy) and SD slot (the bits I always need, these will last me years before they become obsolete)
- daughter boards with sensor systems (the bits I'm updating most often and need to swap out between projects)
Could the existing MicroMod standard be extended or repurposed to support this? Would this require a different keying for safety on IO pins that have a specified direction?
I'm also imagining a tiny base board that carries the SD socket, USB port and power regulators, with a M2 port for the uC on one side and another M2 port for the sensors on the other side.
(On a side note: any relation to the apparently defunct M2.com standard?)
