This mini STM32 development board is based on the STM32L031F6P6, an ARM Cortex-M0+ chip, with USB-C, SWD debugging, a 12-bit ADC and an ultra-low-power design suited to IoT and embedded applications. It is aimed at projects where battery life matters as much as processing power.
The board carries 32 KB of flash, 1 KB of EEPROM and 8 KB of RAM, which is enough for straightforward sensor and control tasks rather than large applications.
The core runs at 32 MHz, the ADC has 12-bit resolution with oversampling, and timers include an LPTIM low-power timer, general-purpose 16-bit timers, an RTC and SysTick. The board has two ultra-low-power comparators, and can be powered at 5 V through USB-C or 3.3 V through the header pins. It includes a reset button, onboard LEDs and is breadboard compatible in a DIP layout, and it works with STM32CubeIDE and STM32duino.
Flash a simple blink or UART example first to confirm the board, toolchain and debugger all talk to each other, before moving on to your own peripherals. Keep the SWD or USB connection short and shielded if you see intermittent flashing failures.
Embedded developers and students who want a very small, low-power STM32 board for battery-sensitive projects, prototyped on a breadboard.
Because the board can run from 3.3V through the header pins as well as from USB-C, you can leave USB attached only for debugging and programming, then switch to a small 3.3V regulator or battery for the finished, battery-powered version of your project.
