Evaluation board with STM32F091VC MCU
Introduction
The STM32091C-EVAL evaluation board is 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, 12bit
ADC, 12bit DAC, two GP comparators, internal SRAM and 256KB
Flash,
Touch sensing,
CEC and SWD debugging support.
The full range of hardware features on the board is able to help you 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.) 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 an embedded
in-circuit debugger and programmer for the STM32 MCU.
