Umptysquatch X: common questions

What microcontroller does the Umptysquatch X use?

The Umptysquatch X is built around the raspberry_pi_pico, from the RP2040/RP2350 family.

How big is the Umptysquatch X PCB?

The Umptysquatch X measures 143.5 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Umptysquatch X?

37 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Umptysquatch X design files?

From the scts-engineering/umptysquatch-10 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Umptysquatch X design in my own project?

The repository has no license, so all rights stay with scts-engineering. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Umptysquatch X 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.
