STM32 small board with the STM32F103ZET6 MCU, full IO expander, JTAG/SWD debug interface
STM32F103ZET6 development board
Overview
Core103Z is a small STM32 development board that features an STM32F103ZET6 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 Core103Z integrates USB communication interface, JTAG/SWD programming/debugging interface, boot mode selection, and so on.
Furthermore, pin headers on the backside allow the Core103Z 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 2.00mm.

Note:
Core103Z 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.
