The motor driver , speaker and mic are great additions. One thing I like About microbit is its power consumption. It can last months on a battery. I just wished it was smaller. As a software guy who plays more with hardware, I really just want a phone with a gpio output, small form factor and low power consumption enough that it could run off solar power. Why can't we have that?
