my dream 75% keeb! made through hack club blueprint!

find all of the files in my KiCad project here! * also contained is a bunch of symbol/footprint files for my keeb + .json files used for the keeb layout plugin

Brew keeb: common questions

What microcontroller does the Brew keeb use?

The Brew keeb is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Brew keeb PCB?

The Brew keeb measures 340.5 × 144 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Brew keeb?

206 components, from 10 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 Brew keeb design files?

From the geg-tech/brew-keeb 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 Brew keeb design in my own project?

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

Can I test firmware for the Brew 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.
