STM 32: common questions

What microcontroller does the STM 32 use?

The STM 32 is built around the STM32F103C8T6, from the STM32 family.

How big is the STM 32 PCB?

The STM 32 measures 38.4 × 32.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STM 32?

28 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the STM 32 design files?

From the DakshLohchab/STM_32_PCB_layout repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the STM 32 design in my own project?

Yes, under the terms of its MIT license, which DakshLohchab chose for the repository.

Can I test firmware for the STM 32 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.
