STM32H750IBK6 Development Board

Overview

**Highlight:** Achieving the remarkable feat of using only 4 layers of board while maintaining an extremely small BGA pitch of 0.65mm for the MCU, resulting in a fully fan-out (NC 1 Pin) configuration! (Signal integrity not guaranteed.**

The peripherals of this project are:

Clock: 24MHz HSE, 32.768KHz LSE, SD3078RTC chip
; Memory: 32-bit wide SDRAM, QSPI interface; FLASH;

Communication interface: SP485, 5V SPI (Transmit only), **USB-A (unverified, only 5V power supply control verified)**, USB-C, TF card slot

; Audio: **WM8978 (unverified)**

; Wireless: ESP32-WROOM-32E (equipped with a USB to serial chip for firmware burning)

; Power supply: IP5310 **(requires a 3.7V lithium battery for normal operation)**;

FPC interface: RGB50Pin (can be directly connected to common 50Pin FFT LCD panels, the board has built-in screen driver), FANKE RGB40Pin **(Incompatible with Zhengdian Atom)**, TouchPad6Pin (IIC interface with built-in external pull-up).

My implemented project file is: [GitHub - KotoriProject/STM32H750_USBdfu_BOOT: USB DFU BOOT based on STM32H750, which realizes reading and programming of 750's FLASH and external W25Q64 through STM32CubeProgrammer's USB interface](https://github.com/KotoriProject/STM32H750_USBdfu_BOOT)
