About the Abhay keyboard PCB

Abhay keyboard is an open source RP2040/RP2350 PCB design by i-am-abhay, published on GitHub. It is a board, with 317 components from 15 distinct parts.

Its main chip is the SC0918, from the RP2040/RP2350 family. Other key parts include the ER_OLEDM0.91_1X-I2C and 74AHCT125. By type, the board carries 79 capacitors, 78 switches, 78 LEDs, 78 diodes, 2 ICs and 1 module.

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

From the project

A keyboard. It features 78 under-lit keys and a .91" OLED display; powered by the Raspberry Pi Pico.

This project is a custom mechanical keyboard that I designed and built from scratch. It features a custom PCB, mechanical switches, RGB lighting, and a 128×32 OLED display. The keyboard runs custom firmware that handles the key matrix, USB input, OLED, and lighting.

I designed the PCB and case myself, then assembled the hardware and wrote the firmware to bring everything together. The goal was to make a keyboard that I could actually use every day while having complete control over both the hardware and software.

Abhay keyboard: common questions

What microcontroller does the Abhay keyboard use?

The Abhay keyboard is built around the SC0918, from the RP2040/RP2350 family.

How many components are on the Abhay keyboard?

317 components, from 15 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 Abhay keyboard design files?

From the i-am-abhay/abhay_keyboard repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Abhay keyboard design in my own project?

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

Can I test firmware for the Abhay 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.
