Kerigokbd: common questions

What microcontroller does the Kerigokbd use?

The Kerigokbd is built around the RP2040, from the RP2040/RP2350 family.

How big is the Kerigokbd PCB?

The Kerigokbd measures 139.5 × 92 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kerigokbd?

80 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kerigokbd design files?

From the kerikun11/kerigokbd repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Kerigokbd design in my own project?

The repository has no license, so all rights stay with kerikun11. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kerigokbd 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.
