Waveshare STM32 STM32H743IIT6 MCU Core board full IO expander JTAG/SWD debug interface CoreH743I Board
Overview
CoreH743I is an STM32 MCU core board designed for STM32H743IIT6, supports further expansion. It is ideal for starting application development with STM32H family.
Minimal ready-to-run system, integrates clock circuit, USB power management, USB connector, etc.
Onboard 64M Bit SDRAM
All the I/O ports are accessible on the pin headers
JTAG/SWD programming/debugging interface
2.0mm header pitch, allowed to be plugged-in your application board

Boot mode selection, for configuring BOOT0 pin
JTAG/SWD interface: for debugging/programming
USB connector, supports Device and/or Host
MCU pins expander, VCC, GND and all the I/O pins are accessible on expansion connectors for further expansion
POWER jumper
VBAT: short the jumper to use system power supply, open it to connect external power, such as battery
VREF: short the jumper to connect VREF+ to VCC, open it to connect VREF+ to other custom pin via jumper wire
OTG jumper
short the jumper when using USB OTG/HOST
open the jumper to disconnect from related I/O port
Note: CoreH743I provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
