STM32 small board with the STM32F407VET6 MCU, full IO expander, JTAG/SWD debug interface
Overview
Core407V is a small STM32 development board that features an STM32F407VET6 device as the microcontroller, supports further expansion. It is ideal for starting application development with STM32F family.
As a minimal ready-to-run system, the Core407V integrates USB communication interface, JTAG/SWD programming/debugging interface, clock circuit, USB power management, boot mode selection, and so on.
Furthermore, pin headers on the backside allow the Core407V 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 2.54mm.

VBAT selection jumper
- short the jumper to use system power supply
- open the jumper to connect the VBAT to external power, such as battery
-
VREF selection jumper
- short the jumper to connect VREF+/VREF- to VCC/GND
- open the jumper to connect VREF+/VREF- to other custom pin via jumper wire
Note:
Core407V provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
Mother board and programmer/debugger in the photos are NOT included in the price.
