STM32 development board designed for STM32F103V series, features the STM32F103VET6 MCU, and integrates various standard interfaces, pretty easy for peripheral expansions.

STM32F103VET6 development board

Open103V is a STM32 development board that features a STM32F103VET6 device as the microcontroller. It supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with STM32F family.

Note: Open103V Standard includes only ONE accessory board -- PL2303 USB UART Board (mini).

  27. JTAG/SWD interface: for debugging/programming;
  28. Boot Mode Selection: for configuring the BOOT0 and BOOT1 pins;
  29. USB Enable Jumper
    • Short the jumper to enable the PC auto detection while USB connecting;
    • Open the jumper to disable;
  30. PS/2 Interface Jumper
    • Short the jumper to connect the PS/2 device to default I/Os;
    • Open the jumper to connect the PS/2 device to custom I/Os via DuPont wires;
  31. LEDs Jumper
    • Short the jumper to connect the LEDs to default I/Os;
    • Open the jumper to connect the LEDs to custom I/Os via DuPont wires;
  32. VBAT Selection Jumper
    • Short the jumper to use system power supply;
    • Open the jumper to connect the VBAT to external power, such as battery;

The Open103V supports programming via STM32 USART bootloader, a USB TO UART accessory board is also provided in the package. 
The Open103V does NOT integrate any debugging function, a debugger is required. 
The Open103V Standard includes only ONE accessory board -- PL2303 USB UART Board (mini).
