Candash: common questions

What microcontroller does the Candash use?

The Candash is built around the STM32F103C8T6, from the STM32 family.

How big is the Candash PCB?

The Candash measures 100 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Candash?

90 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Candash design files?

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

Can I use the Candash design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Candash 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.
