Introduction
The STM320518-EVAL evaluation board is designed as a complete demonstration and
development platform for STMicroelectronic's ARM cortex-M0 core-based
STM32F051R8T6 microcontroller. It features two I2Cs, two SPIs, two USARTs, a 12-bit
ADC, a 12-bit DAC, two GP comparators, internal 8 KB SRAM and 64 KB 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
(motor control connector, RS-232, RS-485, audio DAC, linear sensor, microphone ADC,
TFT LCD, IrDA, IR LED, IR receiver, LDR, MicroSD card, CEC on two HDMI connectors, RF
E2PROM, temperature sensor and so on) and develop your own applications. Extension
headers make it possible to easily connect a daughterboard or wrapping board for your
specific application.
An ST-LINK/V2 is integrated on the board as an embedded in-circuit debugger and
programmer for the STM32 MCU.
