Patriot Companion: common questions

What microcontroller does the Patriot Companion use?

The Patriot Companion is built around the ATMEGA32U4-A, from the AVR/Arduino family.

How big is the Patriot Companion PCB?

The Patriot Companion measures 104.7 × 84.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Patriot Companion?

82 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the Patriot Companion design files?

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

Can I use the Patriot Companion design in my own project?

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

Can I test firmware for the Patriot Companion 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.
