Quokka: common questions

What microcontroller does the Quokka use?

The Quokka is built around the STM32F072CBTx, from the STM32 family.

How big is the Quokka PCB?

The Quokka measures 228.6 × 184.2 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Quokka?

331 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the Quokka design files?

From the ChrisPVille/quokka repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Quokka design in my own project?

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

Can I test firmware for the Quokka 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.
