STM32 STM32F429IGT6 MCU core board, full IO expander, JTAG/SWD debug interface

STM32F429IGT6 development board


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
