Upload the Code and Libraries to the Feather RP2040 Scorpio

After downloading the Project Bundle, plug your Feather RP2040 Scorpio into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called CIRCUITPY. Unzip the folder and copy the following folder and file to the Feather RP2040 Scorpio's CIRCUITPY drive.

  • /lib
  • code.py

Copy the entire lib folder, including all of its contents.

Your Feather RP2040 Scorpio CIRCUITPY drive should resemble the following after copying the lib folder and the code.py file.
