This is a customized version of evyd13's files found here: GH80-1800

Note! I have removed the alternate positioning for varying layouts and included support for Kailh or Gateron Hotswap sockets. The firmware supports only this layout. The PCB supports PCB or Plate mount switches. However the Plate file supports only PCB mount stabilizers. Must use hotswap sockets, otherwise you will have to change the switch footprints to accept solder mount.

Gh80-1800: common questions

What microcontroller does the Gh80-1800 use?

The Gh80-1800 is built around the ATmega32U4, from the AVR/Arduino family.

How big is the Gh80-1800 PCB?

The Gh80-1800 measures 381 × 148.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gh80-1800?

246 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gh80-1800 design files?

From the retoid/G80-1800-Retoid repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gh80-1800 design in my own project?

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

Can I test firmware for the Gh80-1800 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.
