Fourier right: common questions

What microcontroller does the Fourier right use?

The Fourier right is built around the ATMEGA32U2-AU, from the AVR/Arduino family.

How big is the Fourier right PCB?

The Fourier right measures 129.2 × 80.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fourier right?

72 components, from 17 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 Fourier right 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 Fourier right 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 Fourier right 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.
