Tier 1
Raspberry Pi Pico 2 W
The cheap board: best price, needs a sensor module.
What it can sense
| Signal | Support | Notes |
|---|---|---|
| Motion | Supported | Module |
| Sound | Limited | Module + tight RAM |
| Sensor values | Supported |
Before you choose it: setup on your computer
No admin needed, but the first flash needs the BOOTSEL button held while you plug the board in.
Hold the BOOTSEL button while plugging in USB, the first time only.
- In BOOTSEL the board appears as a USB drive named RP2350 (USB ID 2e8a:000f). Copy the .uf2 file onto it.
- Our firmware then runs as a USB serial device (2e8a:0009), so you can reflash without the button: opening that serial port at 1200 baud reboots the board back into BOOTSEL.
- A board that has only ever run a program with no USB (such as the blink example) is invisible to the computer, so it needs the button again.
Checked on the real part
On 1 October 2026 we generated a reference model for this board and ran it on the board itself. It gave the same answer as our server on 32 of 32 test windows.
