Evaluation board with STM32F091VC MCU

The STM32091C-EVAL evaluation board has been designed as a complete demonstration and development platform for STMicroelectronics ARM®cortex®-M0 core-based STM32F091VCT6 microcontroller with two I2C, two SPI, eight USART, one CAN, one 12bit ADC, two 12bit DAC, two GP comparators, internal 32KB SRAM and 256KB Flash, Touch sensing, CEC, SWD debugging support.

The full range of hardware features on the board can be used to evaluate all peripherals (8x USARTs, RS232, RS485, Audio DAC, microphone ADC, touch sensing buttons, TFT LCD, CAN, IrDA, IR LED, IR receiver, LDR, MicroSD card, CEC on two HDMI connectors, smart card slot, RF E2PROM & temperature sensor, etc.) and develop your own applications. Extension headers make it possible to easily connect a daughter board or wrapping board for your specific application.

An ST-LINK/V2-1 is integrated on the board as embedded in-circuit debugger and programmer for the STM32 MCU.
