Phoebe Keyboard: common questions

What microcontroller does the Phoebe Keyboard use?

The Phoebe Keyboard is built around the ATmega32U4-AU, from the AVR/Arduino family.

How big is the Phoebe Keyboard PCB?

The Phoebe Keyboard measures 229.9 × 97.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Phoebe Keyboard?

153 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Phoebe Keyboard design files?

From the Maxr1998/Phoebe_Keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Phoebe Keyboard design in my own project?

The repository has no license, so all rights stay with Maxr1998. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Phoebe 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.
