AVR: common questions

What microcontroller does the AVR use?

The AVR is built around the ATxmega256A3BU-A, from the AVR/Arduino family.

How big is the AVR PCB?

The AVR measures 75 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the AVR?

102 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the AVR design files?

From the reivax-boucoi/AVR repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the AVR design in my own project?

Yes, under the terms of its GPL-3.0 license, which reivax-boucoi chose for the repository.

Can I test firmware for the AVR 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.
