Cross river gorilla: common questions

What microcontroller does the Cross river gorilla use?

The Cross river gorilla is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Cross river gorilla PCB?

The Cross river gorilla measures 295.3 × 110.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cross river gorilla?

150 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cross river gorilla design files?

From the KingMalur/Keyboards repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Cross river gorilla design in my own project?

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

Can I test firmware for the Cross river gorilla 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.
