About the Pcb miny

Pcb miny is an open source RP2040/RP2350 PCB design by zzeneg, published on GitHub under the MIT license. It is a 2-layer board measuring 149.8 × 109.8 mm, with 121 components from 12 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. By type, the board carries 35 switches, 34 LEDs, 34 diodes, 7 capacitors, 3 connectors and 1 jumper.

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 miny: common questions

What microcontroller does the Pcb miny use?

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

How big is the Pcb miny?

The Pcb miny measures 149.8 × 109.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb miny?

121 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb miny 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 miny 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 miny 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.
