Core103V STM32F1 Core 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.
