STM32 Small Board With The STM32F103VET6 MCU, Full IO Expander, JTAG/SWD Debug Interface

STM32F103VET6 development board


Core103V is a small STM32 development board that features an STM32F103VET6 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 Core103V integrates USB communication interface, JTAG/SWD programming/debugging interface, clock circuit, boot mode selection, and so on.

Furthermore, pin headers on the backside allow the Core103V 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.

AMS1117-3.3 (on bottom side): 3.3V voltage regulator Power supply switch, powered from 5Vin or USB connection Boot mode selection, for configuring BOOT0 pin Boot mode selection (on bottom side), for configuring BOOT1 pin Power indicator VBUS LED Reset button 8M crystal oscillator 32.768K crystal (on bottom side), for internal RTC with calibration JTAG/SWD interface: for debugging/programming USB connector, used for establishing USB communication between PC and the STM32 development board IO expander (including VCC/GND), all the I/O pins are accessible on expansion connectors for further expansion 5Vin pinheader, 5V power supply input USB enable jumper
  • short the jumper to enable USB function
  • open the jumper to disable, as well as taking up no I/O port
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



Core103V 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.
