Pheromone keyboard: common questions

What microcontroller does the Pheromone keyboard use?

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

How big is the Pheromone keyboard PCB?

The Pheromone keyboard measures 304 × 99 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pheromone keyboard?

146 components, from 22 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 Pheromone keyboard design files?

From the luantty2/pheromone_keyboard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pheromone keyboard design in my own project?

The repository has no license, so all rights stay with luantty2. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Pheromone keyboard 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.
