Keyboard v1: common questions
What microcontroller does the Keyboard v1 use?
The Keyboard v1 is built around the ATMEGA32U4-AU, from the AVR/Arduino family.
How big is the Keyboard v1 PCB?
The Keyboard v1 measures 297 × 113 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Keyboard v1?
140 components, from 74 distinct parts. The full bill of materials is listed on this page.
Where can I download the Keyboard v1 design files?
From the augustt198/keyboard-v1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Keyboard v1 design in my own project?
The repository has no license, so all rights stay with augustt198. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Keyboard v1 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.
