Evaluation board with STM32H743XI MCU
Introduction
The STM32H743I-EVAL Evaluation board is a high-end development platform for the ARM
®
Cortex
®
-M7-based STM32H743XI microcontroller. The STM32H743I-EVAL Evaluation
board provides acces
s to all the STM32 peripherals for user applications and includes an
embedded ST-LINK debugger/programmer. The full range of the hardware features on the
STM32H743I-EVAL Evaluation board, helps to evaluate all the peripherals (USB OTG HS
and FS, Ethernet, FD-CAN, USART, Audio DAC and ADC, digital microphone, SRAM,
SDRAM, NOR Flash, Twin Quad-SPI Flash, microSD
™
3.0 card and 5.7” 640x480 TFT
color LCD with touch screen) and to develop applications.
The expansion connectors provide an easy way to add specialized features, while ETM
trace is supported through external probes.
