Core407I is a STM32F407IGT6  based small STM32 development board .It supports further expansion. It is ideal for starting application development with STM32F family.

Core407I integrates USB communication interface, JTAG/SWD programming/debugging interface, clock circuit, USB power management, boot mode selection etc.

Furthermore, pin headers on the backside allow the Core407I to be plugged-in your application board and act as the MCU core circuit in your system. All the I/O ports are accessible on the pin headers, and the header pitch is designed as 2.0mm to achieve smaller pcb size.
