Mikroelektronika MINI-M0 for STM32
Mikroelektronika MINI-M0 for STM32 is a small ARM® Cortex™-M4 development board containing a STM32F051R8 microcontroller. It fits perfectly into a standard DIP40 socket. The board is equipped with 16MHz SMD crystal oscillator, and 32.768KHz crystal which can be used for an internal RTCC module. It has a reset button and three signal LEDs. The board comes preprogrammed with a fast USB-UART bootloader, so no external programmers are needed for development. It operates on 3.3V power supply. An on-board voltage regulator allows the board to be powered directly from a USB cable.
