Split keyboard: common questions

What microcontroller does the Split keyboard use?

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

How big is the Split keyboard PCB?

The Split keyboard measures 258.7 × 103.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Split keyboard?

90 components, from 6 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 design files?

From the Randomcoder323/split-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 Split keyboard design in my own project?

The repository has no license, so all rights stay with Randomcoder323. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Split keyboard 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.
