Corne Light: common questions

What microcontroller does the Corne Light use?

The Corne Light is built around the ATMEGA32U2-AU, from the AVR/Arduino family.

How big is the Corne Light PCB?

The Corne Light measures 275.5 × 105.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Corne Light?

93 components, from 9 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 Corne Light design files?

From the IndianBoy42/keyboard-pcbs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Corne Light design in my own project?

The repository has no license, so all rights stay with IndianBoy42. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Corne Light 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.
