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 waiting Flash, etc., and the price is right, 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, debugging, serial port, U disk download three in one.

Onboard resource details

STM32H750VBT6 high-performance ARM microprocessor

STM32F103CBT6 microprocessor used as ST-Link function

One RGB LED

The 16Mbit QSPI-Flash can realize the 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 can be used to drive a 3.2-inch LCD dedicated to the Arduino Mega2560 (this screen is chosen over other screens because this screen is very cheap and the display is very good), LCD driver model: ILT9481

An LM358 op amp is used to improve the DAC output capability and can be used normally under 5V power supply. Or replace it with LMV358 to use it under 3.3V power supply

A super capacitor is used as RTC backup power supply.

Micro-USB interface with self-recovery fuse.

You can set whether the LPUART1 is connected to the on-board ST-LINK through the jumper cap (left side silk screen SERIAL header, 1 ~ 2, 3 ~ 4 can be accessed by shorting the jumper cap)

Note: Because of port multiplexing, there is a situation where one wire belongs to multiple networks in the schematic. However, when switching to PCB, a network will be randomly reserved. This will lead to a different number of schematics and PCB networks. This situation does not affect normal editing and use. Before using, please flash the ST-LinkV2.1 Bootloader for the onboard STM32F103CB through another ST-Link. After flashing, connect the development board via USB. After updating the firmware using ST-Link Utilities, you can use the on-board ST-Link normally. All the features.
