This is only sort of a new design. I’ve used this TB6621FNG dual motor driver chip on a number of my boards prior to this one. I basically just took one of my existing boards and shuffled things around a bit to fit the Raspberry Pi Zero form factor.
In this photo, I’m using it with a Pi A+ while writing some Python code to test it out. Eventually (when I can get more than one Pi Zero), I plan to use this in a stack, with a Pi Zero, my LiPoly battery board, and my USB hub board for WiFi.
