STM32 STM32H743IIT6 MCU Core Board, Full IO Expander, JTAG/SWD Debug Interface

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
