Pre-built UF2s for Arduino-based Learning System Guides

We loved how easy it was to load CircuitPython programs onto boards, and we’re working to bring that to our Arduino-based guides.

Now, select Arduino-based guides have their code built into self-contained uf2 files. To find the latest, visit and choose the zip file for your board.

Send your board into bootloader mode, typically by double-clicking the reset button. Open up the zip file you downloaded earlier, and drag the uf2 file for the project you’re following to the BOOT disk that appears.

Check back, as we’ll be adding pre-built uf2 files for more of our guides as time goes by!
