About the KBoard PCB

KBoard is an open source RP2040/RP2350 PCB design by mihranrazaa, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 395.5 × 135 mm, with 180 components from 12 distinct parts.

Its main chip is the Raspberry_Pi_Pico, from the RP2040/RP2350 family. By type, the board carries 92 switches, 87 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

KBoard: common questions

What microcontroller does the KBoard use?

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

How big is the KBoard PCB?

The KBoard measures 395.5 × 135 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KBoard?

180 components, from 12 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 KBoard design files?

From the mihranrazaa/KBoard 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 KBoard design in my own project?

Yes, under the terms of its GPL-3.0 license, which mihranrazaa chose for the repository.

Can I test firmware for the KBoard 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.
