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
