Ergodonk simple: common questions

What microcontroller does the Ergodonk simple use?

The Ergodonk simple is built around the Pico, from the RP2040/RP2350 family.

How big is the Ergodonk simple PCB?

The Ergodonk simple measures 216.6 × 155.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ergodonk simple?

144 components, from 22 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 Ergodonk simple design files?

From the JellyTitan/ErgoDonk 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 Ergodonk simple design in my own project?

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

Can I test firmware for the Ergodonk simple 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.
