Mikroe 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 pre-programmed 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. Learn More
