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 1.2 mm thick.

How many components are on the Gh80-1800?

272 components, from 31 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 Gh80-1800 design files?

From the evyd13/gh80-series 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 Gh80-1800 design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which evyd13 chose for the repository.

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.
