Apologies in advance as I suspect this a silly question.
I'm currently building an emulator console into an old Game Gear using a Pi Zero W. My plan is to use a Teensy LC to manage the controls. I'm a complete noob so I'm not clear on how to connect the Teensy to the Pi. Does it have to be via the Micro USB port? I'm hoping to avoid this as the Pi Zero only has one USB port and I plan to use this for a USB soundcard so I can hook up the original Game Gear soundboard (tested successfully on a Pi 2). I can get a 5v supply from the original (re-capped) Game Gear power supply but then there would be no way of getting a signal from the Teensy to the Pi...
Any ideas?
