Flashing:

1. Download the latest version of CircuitPython for the Raspberry Pi Pico.
2. Connect the cart using a USB A to C cable and drop the CircuitPython .uf2 file onto the device.
3. Once the CircuitPy device pops up, move the files that correspond to your display from "Circuitpy Files" onto your device. Choose the correct resolution matching the display installed.
4. Drop a 152x152 or 200x200 1 or 2 bit BMP onto the device to update the e-ink display image. Choose the correct resolution matching the display installed.
