A small-footprint, custom development PCB for the STM32 platform
-
This board's MCU is an STM32F072CBT6, meaning it is a higher-end 48-pin LQFP chip with 128kB of flash and an ARM Cortex-M0 core.
-
The board supports CANbus, LINbus, I2C, SPI, USB, and UART. Flashing can be achieved through an ST-LINK external flasher using the SWD protocol.
-
The board is powered through a Micro-USB port and draws very little current. Power conversion occurs through a 5~3.3V linear regulator.
-
The board has a 32.768kHz clock for RTC capabilities as well as an 8MHz system clock. It also features an indicator LED and a reset button.
-
The footprint of the board is 19x52 mm and its 2.54 mm pitch headers allow it to be used with standard breadboards.

Questions
How big is the Stm32-dev board PCB?
It measures 19.3 × 52.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32-dev board use?
30 parts, built around the STM32F072CBT6 and TC1262-3.3VDB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Stm32-dev board KiCad files?
From the ShaneTWilliams/stm32-dev-board repository on GitHub, at the commit this page was made from: the board is board_files/stm32-dev-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32-dev board design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
