The KiCad project lives in the dac63701/60WKeyboard repository on GitHub; these links point at the commit this page was built from.

60WKeyboard: common questions

What microcontroller does the 60WKeyboard use?

The 60WKeyboard is built around the NRF52840, from the Nordic nRF family.

How big is the 60WKeyboard PCB?

The 60WKeyboard measures 285 × 95 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the 60WKeyboard?

296 components, from 40 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 60WKeyboard design files?

From the dac63701/60WKeyboard 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 60WKeyboard design in my own project?

The repository has no license, so all rights stay with dac63701. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 60WKeyboard 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.
