SkullPad: common questions

What microcontroller does the SkullPad use?

The SkullPad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the SkullPad PCB?

The SkullPad measures 61.7 × 60.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SkullPad?

14 components, from 4 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 SkullPad design files?

From the Stempell/SkullPad 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 SkullPad design in my own project?

Yes, under the terms of its MIT license, which Stempell chose for the repository.

Can I test firmware for the SkullPad 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.
