About the Keyboard PCB

Keyboard is an open source Raspberry Pi PCB design by kermitsgonnakermicide, published on GitHub. It is a 2-layer board measuring 291.4 × 131 mm, with 130 components from 13 distinct parts.

Its main chip is the RaspberryPi_Pico_W, from the Raspberry Pi family. By type, the board carries 62 switches, 61 diodes, 6 connectors and 1 module.

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

From the project

a modular keyboard(w/ i2c!)

Lattice also comes with three modules(as of now), which are: - a 16 key macropad with an OLED - a 3 slider, two encoder module i'm calling the sliderpad - a 32x4 RGB LED(specifically the WS2812B-2020) matrix that slides in the empty top bit of the keyboard(connected by 2.54 mm pins because I didnt trust the current limits of the magnetic connectors)

Each module features a xiao rp2040 to run everything else on it because its so smol and cute :3

Keyboard: common questions

What microcontroller does the Keyboard use?

The Keyboard is built around the RaspberryPi_Pico_W, from the Raspberry Pi family.

How big is the Keyboard PCB?

The Keyboard measures 291.4 × 131 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard?

130 components, from 13 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 Keyboard design files?

From the kermitsgonnakermicide/Lattice 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 Keyboard design in my own project?

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

Can I test firmware for the Keyboard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
