Centipede-32z: common questions

What microcontroller does the Centipede-32z use?

The Centipede-32z is built around the RP2350B, from the RP2040/RP2350 family.

How big is the Centipede-32z PCB?

The Centipede-32z measures 97.6 × 96 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Centipede-32z?

118 components, from 35 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 Centipede-32z design files?

From the strickyak/copico-centipede 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 Centipede-32z design in my own project?
