STM32H750 development board

The H7 series is ST's latest high-performance ARM microprocessor product line, and the STM32H750VBT6 is the most cost-effective one in the H7 product line. It has all the features of the H7 series, such as Cortex-M7 core, 400Mhz main frequency, 1MB distribution SRAM, 16K instruction and data cache. 128KB zero-wait Flash, etc., and the price is suitable, which is very suitable for high-performance embedded application development.

This development board is based on the STM32STM32H750VBT6 core and can be used for evaluation, learning and development of H7 series microprocessors.

Onboard ST-Link V2.1, three-in-one debugging, serial port, and U disk download.

Onboard resource details

• STM32H750VBT6 high-performance ARM microprocessor
• STM32F103CBT6 microprocessor used as ST-Link function
• One RGB common anode LED light
• 16Mbit QSPI-Flash can implement xIP function (QSPI-BANK2) and can be changed to a compatible larger-capacity NOR-Flash (such as W25Q128).
• Micro-SD card interface
• An LCD interface that can be used to drive a 3.2-inch LCD dedicated to ArduinoMega2560 (choose this instead of other screens because this screen is very cheap and has a good display effect), LCD driver model: ILT9481
• An LM358 op amp is used to improve the DAC output capability and can be used normally under a 5V power supply. Or replace it with LMV358 yourself to use it with 3.3V power supply
• A supercapacitor serves as RTC backup power supply.
• micro-USB interface with resettable fuse.
• You can use the jumper cap to set whether LPUART1 is connected to the onboard ST-LINK (the silk screen SERIAL pins on the left, 1~2, 3~4 can be connected by shorting the jumper cap)

Note: Due to port reuse, there may be a situation where one wire belongs to multiple networks in the schematic diagram. But when converting to PCB, a network will be randomly retained. This will cause the schematic and PCB to have different numbers of nets. This situation does not affect normal editing and use. Before use, please flash the ST-LinkV2.1 Booloader for the onboard STM32F103CB through another ST-Link. After flashing, connect the development board through USB. After updating the firmware using ST-Link Utilities, you can use the onboard ST-Link normally. all functions.
