KEYBOARDTOP: common questions

What microcontroller does the KEYBOARDTOP use?

The KEYBOARDTOP is built around the RP2040, from the RP2040/RP2350 family.

How big is the KEYBOARDTOP PCB?

The KEYBOARDTOP measures 318.5 × 163 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KEYBOARDTOP?

200 components, from 107 distinct parts. The full bill of materials is listed on this page.

Where can I download the KEYBOARDTOP design files?

From the bartekp-i/myMechanicalKeyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the KEYBOARDTOP design in my own project?

Yes, under the terms of its MIT license, which bartekp-i chose for the repository.

Can I test firmware for the KEYBOARDTOP 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.
