About the Mechanical-Keyboard PCB

Mechanical-Keyboard is an open source RP2040/RP2350 PCB design by Bihyungbetter, published on GitHub. It is a 2-layer board measuring 360 × 155 mm, with 249 components from 12 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. Other key parts include the ER_OLEDM0.91_1X-I2C. By type, the board carries 80 switches, 75 LEDs, 75 diodes, 16 capacitors, 1 IC and 1 module.

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

From the project

Custom 75-key RP2040 mechanical keyboard with rotary encoder, OLED, and RGB lighting

This Mechanical Keyboard is a custom 75-key Alice mechanical keyboard built around a Raspberry Pi Pico / RP2040. It has a 5×15 key matrix, per-key SK6812 MINI-E RGB lighting, an EC11 rotary encoder with push switch, and a 128×32 I2C OLED display. I learned how to stitch together different parts, and I made this in hopes of a more ergonomic keyboard.

I estimate I need 150$ for funding. Any extra funds will be returned to Hack Club

Mechanical-Keyboard: common questions

What microcontroller does the Mechanical-Keyboard use?

The Mechanical-Keyboard is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Mechanical-Keyboard PCB?

The Mechanical-Keyboard measures 360 × 155 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mechanical-Keyboard?

249 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 Mechanical-Keyboard design files?

From the Bihyungbetter/Mechanical-Keyboard 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 Mechanical-Keyboard design in my own project?

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

Can I test firmware for the Mechanical-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.
