Pico Button Board: common questions

What microcontroller does the Pico Button Board use?

The Pico Button Board is built around the SC1632, from the RP2040/RP2350 family.

How big is the Pico Button Board?

The Pico Button Board measures 55.9 × 111.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pico Button Board?

201 components, from 78 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Pico Button Board design files?

From the RealtimeRoboticsGroup/electrical repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Pico Button Board design in my own project?

It is published under SHL-2.1, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Pico Button Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
