STMicroelectronics Discovery Kit with STM32H7B3LI MCU

For demonstration and development of STMicroelectronics Arm® Cortex®-M7 core-based STM32H7B3LIH6QU MCU

STMicroelectronics STM32H7B3I-DK Discovery Kit is a complete demonstration and development platform for STMicroelectronics Arm® Cortex®-M7 core-based STM32H7B3LIH6QU microcontroller, set apart by its internal memory for graphics.

With a full range of hardware features available, the STM32H7B3I-DK is used as a reference design for user application development before porting to the final product, thus simplifying and enhancing the graphic application development process.

The full range of hardware features available on the STM32H7B3I-DK helps users evaluate almost all peripherals (such as USB OTG_HS, microSD, USART, FDCAN, audio DAC stereo with audio jack input and output, camera, SDRAM, Octo-SPI Flash memory and RGB interface LCD with capacitive touch panel). ARDUINO® Uno V3 connectors provide easy connection to extension shields or daughterboards for specific applications.

STLINK-V3E is integrated into the board, as an embedded in-circuit debugger and programmer for the STM32 MCU and the USB Virtual COM port bridge.

The STMicroelectronics STM32H7B3I-DK board comes with the STM32CubeH7 MCU Package, which provides an STM32 comprehensive software HAL library as well as various software examples.
