Install CircuitPython

Install CircuitPython

You'll need: the Prop-Maker Feather, a USB-C data cable, a computer · Time: 10 minutes

CircuitPython is the small programming language that runs Lola's code. You only do this once per board.

Steps

1. Go to the CircuitPython page for the Prop-Maker Feather.
2. Download the newest 9.x version (a .uf2 file). Not 10.x — Lola's code is written for version 9.
3. Plug the Feather into your computer with the USB cable.
4. Hold down the BOOT button on the Feather.
5. While holding it, press and let go of the RESET button.
6. Let go of BOOT. A drive called RPI-RP2 appears on your computer.
7. Drag the .uf2 file onto RPI-RP2.
8. Wait. The drive disappears and a new one called CIRCUITPY appears.

✅ It should look like this

A drive called CIRCUITPY with a file called boot_out.txt in it. Open that file: the first line says Adafruit CircuitPython 9.….

⚠️ Something went wrong?

Problem	Fix
No drive appears at all	Try another cable: many only charge. Try another USB port.
RPI-RP2 doesn't appear	Hold BOOT before pressing RESET, and keep holding until you've let go of RESET.
CIRCUITPY never appears after copying	Wait 30 seconds. Unplug and plug back in. Check you downloaded the file for the Prop-Maker Feather, not another board.

More detail (for tinkerers)

• The robot was last tested on CircuitPython 9.2.8. Upgrading to 10.x isn't supported yet: libraries and settings.toml handling may differ.
• The .mpy libraries in PropMaker_Feather/lib/ are compiled for CircuitPython 9. If you ever update them, get the 9.x bundle from circuitpython.org/libraries.

Next: Copy the firmware.
