Mykeeb: common questions

What microcontroller does the Mykeeb use?

The Mykeeb is built around the ProMicro, from the AVR/Arduino family.

How big is the Mykeeb PCB?

The Mykeeb measures 159.5 × 119.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mykeeb?

115 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mykeeb 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 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 without the hardware?

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