About the Split-Keyboard with-Joystick PCB

Split-Keyboard with-Joystick is an open source Nordic nRF PCB design by Shadow220108, published on GitHub. It is a 2-layer board measuring 312.4 × 114.1 mm, with 108 components from 7 distinct parts.

Its main chip is the XIAO-nRF52840-SMD, from the Nordic nRF family. Other key parts include the 74HC165. By type, the board carries 56 diodes, 48 switches and 3 ICs.

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

From the project

Its a split keyboard custom designed for most effective use ( for me ) with an integrated trackball , maximizing productivity and ergonomics

Its a split keyboard custom designed for most effective use ( for me ) with an integrated joystick ( to be used as cursor) , maximizing productivity and ergonomics I am using XIAO NRF58240 rather than ESP32 cause the zmk firmware support is currently experimental/non-existent in the main branch, and the battery life of the keyboard which will be reduced to days rather than months in NRF58240

Split-Keyboard with-Joystick: common questions

What microcontroller does the Split-Keyboard with-Joystick use?

The Split-Keyboard with-Joystick is built around the XIAO-nRF52840-SMD, from the Nordic nRF family.

How big is the Split-Keyboard with-Joystick PCB?

The Split-Keyboard with-Joystick measures 312.4 × 114.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Split-Keyboard with-Joystick?

108 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 Split-Keyboard with-Joystick design files?

From the Shadow220108/Split-Keyboard-with-Joystick 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 Split-Keyboard with-Joystick design in my own project?

The repository has no license, so all rights stay with Shadow220108. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Split-Keyboard with-Joystick 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.
