About the Bykeeb PCB

Bykeeb is an open source Nordic nRF PCB design by sadekbaroudi, published on GitHub. It is a 2-layer board measuring 246.5 × 92.8 mm, with 84 components from 7 distinct parts.

Its main chip is the XIAO-BLE, from the Nordic nRF family. By type, the board carries 38 switches, 36 diodes, 2 ICs, 2 modules and 2 connectors.

It belongs with the keyboards and iot & wireless designs in this gallery.

From the project

This is a 36 key wireless keyboard using a seeed xiao nrf52840 controller, supporting choc, gateron low profile, and MX switches.

Firmware is done in ZMK, and can be found in the zmk-fingerpunch-keyboards github repository, specifically in the boards/shields/bykeeb directory.

Use the gerber.zip found in the pcb directory. If you are using jlcpcb, you can also use the bom.csv and positions.csv to do PCBA

Bykeeb: common questions

What microcontroller does the Bykeeb use?

The Bykeeb is built around the XIAO-BLE, from the Nordic nRF family.

How big is the Bykeeb PCB?

The Bykeeb measures 246.5 × 92.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bykeeb?

84 components, from 7 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 Bykeeb design files?

From the sadekbaroudi/bykeeb 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 Bykeeb design in my own project?

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

Can I test firmware for the Bykeeb without the hardware?

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