XCore407I is an STM32 MCU core board that features the STM32F407IGT6 on board.

• Clock circuit, USB power management
• Onboard devices: USB HS PHY、Ethernet PHY、1G Bit NandFlash
• Connectors：USB HS (mini / type A), USB FS (mini), Ethernet (RJ45)
• All the idle I/O ports are accessible on the pin headers
• 2.0mm pin header pitch, smaller size, easier to integrate into user system
