Mk keeb: common questions

What microcontroller does the Mk keeb use?

The Mk keeb is built around the RP2040_Stamp, from the RP2040/RP2350 family.

How big is the Mk keeb PCB?

The Mk keeb measures 371.5 × 152.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mk keeb?

220 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mk keeb design files?

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

Can I use the Mk keeb design in my own project?

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

Can I test firmware for the Mk keeb without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
