Zirconia: common questions

What microcontroller does the Zirconia use?

The Zirconia is built around the STM32F411CEU6, from the STM32 family.

How big is the Zirconia PCB?

The Zirconia measures 39 × 91 mm, has 2 copper layers and is 0.6 mm thick.

How many components are on the Zirconia?

90 components, from 38 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 Zirconia design files?

From the viola0222/zirconia 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 Zirconia design in my own project?

Yes, under the terms of its Apache-2.0 license, which viola0222 chose for the repository.

Can I test firmware for the Zirconia without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
