About the Custom keyboard PCB

Custom keyboard is an open source RP2040/RP2350 PCB design by hrushikbarani-hub, published on GitHub. It is a 2-layer board measuring 60 × 66 mm, with 16 components from 5 distinct parts.

Its main chip is the Orpheus Pico / Pico compatible, from the RP2040/RP2350 family. By type, the board carries 6 switches, 6 diodes, 2 resistors, 1 IC and 1 connector.

It belongs with the keyboards and displays & leds designs in this gallery.

Custom keyboard: common questions

What microcontroller does the Custom keyboard use?

The Custom keyboard is built around the Orpheus Pico / Pico compatible, from the RP2040/RP2350 family.

How big is the Custom keyboard PCB?

The Custom keyboard measures 60 × 66 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom keyboard?

16 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Custom keyboard design files?

From the hrushikbarani-hub/custom-keyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Custom keyboard design in my own project?

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

Can I test firmware for the Custom keyboard 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.
