Mykeeb v7a4: common questions

What microcontroller does the Mykeeb v7a4 use?

The Mykeeb v7a4 is built around the xiao-ble, from the Nordic nRF family.

How big is the Mykeeb v7a4 PCB?

The Mykeeb v7a4 measures 162.3 × 124.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mykeeb v7a4?

59 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mykeeb v7a4 design files?

From the maxhbr/zmk-stuff repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Mykeeb v7a4 design in my own project?

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

Can I test firmware for the Mykeeb v7a4 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.
