Volksz2: common questions

What microcontroller does the Volksz2 use?

The Volksz2 is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Volksz2 PCB?

The Volksz2 measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Volksz2?

30 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Volksz2 design files?

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

Can I use the Volksz2 design in my own project?

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

Can I test firmware for the Volksz2 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.
