A small STM32 development board featuring:
-STM32F030F4P6 MCU (TSSOP20 package)
-external 8MHz crystal as HSE clock
-break-out of all available MCU pins
-Mini USB port for powering the project
-reset tactile button
-boot mode selector jumper on board
-1x VCC presence indicator LED, indicating 3V3 from the LDO on-board voltage regulator
-1x +5V presence indicator LED, indicating +5V via USB
-EXT_VIN for supplying the board via an external power supply (USB must be disconnected in this case!)
-UART header for programming the MCU via serial bootloader
-programmable user LED on pin PB1 (PWM)
Looks like a nice, neat little dev board.
