Opena3xx hardware controller board: common questions

What microcontroller does the Opena3xx hardware controller board use?

The Opena3xx hardware controller board is built around the C132132, from the Raspberry Pi family.

How big is the Opena3xx hardware controller board?

The Opena3xx hardware controller board measures 156.3 × 80.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Opena3xx hardware controller board?

49 components, from 14 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 Opena3xx hardware controller board design files?

From the OpenA3XX/opena3xx.schematics repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Opena3xx hardware controller board design in my own project?

Yes, under the terms of its GPL-3.0 license, which OpenA3XX chose for the repository.

Can I test firmware for the Opena3xx hardware controller board without the hardware?

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