Stm32f042: common questions

What microcontroller does the Stm32f042 use?

The Stm32f042 is built around the STM32F042C6Tx, from the STM32 family.

How big is the Stm32f042 PCB?

The Stm32f042 measures 78.5 × 64.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Stm32f042?

42 components, from 25 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 Stm32f042 design files?

From the eddyem/tsys01 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Stm32f042 design in my own project?

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

Can I test firmware for the Stm32f042 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.
