Campus keyboard: common questions

What microcontroller does the Campus keyboard use?

The Campus keyboard is built around the C112161, from the AVR/Arduino family.

How big is the Campus keyboard PCB?

The Campus keyboard measures 307 × 85 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Campus keyboard?

242 components, from 22 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 Campus keyboard design files?

From the flurples/campus 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 Campus keyboard design in my own project?

Yes, under the terms of its GPL-3.0 license, which flurples chose for the repository.

Can I test firmware for the Campus keyboard 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.
