Avain: common questions

What microcontroller does the Avain use?

The Avain is built around the rp2040-zero, from the RP2040/RP2350 family.

How big is the Avain PCB?

The Avain measures 314.4 × 98.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Avain?

200 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Avain design files?

From the digitarhythm/AVAIN repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Avain design in my own project?

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

Can I test firmware for the Avain without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
