LEGO Technic Mini Tank with ESP32 & 2x NEMA 8 Stepper Motors | #LEGO #Technic #minifig #minitank

Fun little project using a Feather ESP32, “Joystick to Tank Drive” controller software, a custom Featherwing (!), a pair of Pololu DRV8835 motor drivers & NEMA 8 steppers, and even some custom 3D-printed parts. All the files are provided so you can easily order your own Featherwings for this or another project (the board design can actually accommodate up to 4 Pololu DRV8835s!). So cool!

For this project I used 2x NEMA 8 steppers motor to drive a tank built from LEGO Technic bricks. The microcontroller is an Adafruit Feather ESP32.
