LEGO Technic Tank with Stepper Motors and @Adafruit #Feather HUZZAH #ESP32 Controller
Jason on Hackaday.io describes building LEGO Technic motorized projects. He’s taken an Adafruit Feather HUZZAH ESP32 board and added his own custom-built FeatherWing using DRV8835 drivers to run NEMA 8 stepper motors. A very compact design!
You can also see the project on Hackaday.
Here are two videos, one of the tank, the other of building the driver Wing
