MMv3

MMv3 is the 3rd generation robot platform used to teach the IEEE Micromouse DeCal at UC Berkeley. It was designed with usability, manufacturability, size, and cost in mind.

Setup

1. Follow the assembly instructions in lab1 using the latest BOM.
2. Plug mouse into your computer and upload the latest firmware.uf2 (see releases) by dragging the file into the RPI-RP2 folder that shows up. It should disappear and reappear as a CIRCUITPY folder.
   • If you've uploaded firmware before, you'll need to hold the BOOTSEL button on the Pi Pico while plugging in.
3. Download the latest CircuitPython libraries (Bundle for Version 7.x) and upload the following ones to the lib/ folder on your mouse.
   • adafruit_motor/
   • adafruit_onewire/
   • neopixel.mpy

Labs

Skeleton lab code, lab documents, and solutions are stored in labs/, docs/, and solutions/, respectively. To get started with a lab, simply copy the contents of the folder over to the CircuitPython drive and edit files from there.
