Unrouted: common questions

What microcontroller does the Unrouted use?

The Unrouted is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the Unrouted PCB?

The Unrouted measures 44.5 × 57.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Unrouted?

63 components, from 31 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 Unrouted design files?

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

Can I use the Unrouted design in my own project?

Yes, under the terms of its MIT license, which plertvilai chose for the repository.

Can I test firmware for the Unrouted 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.
