About the Pcb

Pcb is an open source RP2040/RP2350 PCB design by zzeneg, published on GitHub under the MIT license. It is a 2-layer board measuring 139.8 × 110.8 mm, with 113 components from 7 distinct parts.

Its main chip is the rp2040-zero, from the RP2040/RP2350 family. By type, the board carries 39 diodes, 35 switches, 31 LEDs and 1 IC.

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

From the project

Half-keyboard optimized for gaming

- 31 regular MX or KS-33/27 switches - 5-way switch - 3 push buttons - per-key LEDs - 3D printed case

Optimized for regular WASD setup similar to a normal keyboard, to avoid (or at least minimize) remapping keys for games.

No layer-tap and mod-taps to avoid conflicts (many games require mod presses or holding alpha keys).

1 additional layer to access missing half of keyboard.

Pcb: common questions

What microcontroller does the Pcb use?

The Pcb is built around the rp2040-zero, from the RP2040/RP2350 family.

How big is the Pcb?

The Pcb measures 139.8 × 110.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

113 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb design files?

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

Can I use the Pcb design in my own project?

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

Can I test firmware for the Pcb 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.
