KeeBoard: common questions

What microcontroller does the KeeBoard use?

The KeeBoard is built around the ATmega32U4-A, from the AVR/Arduino family.

How big is the KeeBoard PCB?

The KeeBoard measures 351.9 × 99.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KeeBoard?

267 components, from 25 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 KeeBoard design files?

From the scattercat-123/KeeBoard 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 KeeBoard design in my own project?

The repository has no license, so all rights stay with scattercat-123. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the KeeBoard 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.
