🔌

Set up your board

New board, or one that forgot its WiFi? Three small steps and you're ready to play.

🔌 Board setup in 3 steps

1

Power it up. Plug your board into USB. A brand-new (or stuck) board gets its starter firmware right here in the browser: open the flasher and press Connect.

2

Join WiFi. The board opens its own hotspot on first start. Connect to it and pick your home WiFi at 192.168.4.1.

3

Say hello. The board shows its ID on the LED screen. Open Start coding, press the ⚙ gear and type the ID in — done!
