Brand waveshare Model Core103V Quantity 1 Piece Color Green Material CCL+PCB board+Semiconductor Chipset STM32F103VET6 English Manual / Spec Yes Other Features 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.
