KeyBoard: common questions

What microcontroller does the KeyBoard use?

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

How big is the KeyBoard PCB?

The KeyBoard measures 89.6 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KeyBoard?

24 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the KeyBoard design files?

From the Mani47e/KeyBoard_PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the KeyBoard design in my own project?

The repository has no license, so all rights stay with Mani47e. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the 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.
