Overview

Core429I is an STM32 MCU core board designed for STM32F429IGT6, supports further expansion. It is ideal for starting application development with STM32F 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

Note:
Mother board or programmer/debugger in the photo is NOT included in the price.
Core429I provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
