GH60: common questions

What microcontroller does the GH60 use?

The GH60 is built around the ATMEGA32U4, from the AVR/Arduino family.

How big is the GH60 PCB?

The GH60 measures 285 × 94.6 mm, has 2 copper layers and is 1.6002 mm thick.

How many components are on the GH60?

303 components, from 19 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 GH60 design files?

From the BenjaminJAnderson/Orthodox repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the GH60 design in my own project?

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

Can I test firmware for the GH60 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.
