Rover Chassis for micro:bit and Pololu Track
thingiverse
Update: Waveshare Motor Driver fits snugly in micro:bit and Raspberry Pi Zero versions V3.4. I removed the mount for the ball caster since it looked awkward with tires on this model. The battery holder for two AA batteries fits in two different directions. I modified a dozer blade from my smaller Sumo bot to fit this chassis perfectly, giving it a convenient hole for a switch. This simple Chassis is designed specifically for micro:bit and Kittenbot Robotbit robotics expansion boards. I paired 3V or 6V metal gear micro motors with Pololu 30T track sets. If you prefer wheels over tracks, you can easily swap them out for Pololu 3/8" ball casters instead. The dozer blade from my other Sumo bot is a perfect fit, as seen in the picture with the yellow dozer blade attached.
