Overview
Core103R is an STM32 MCU core board designed for STM32F103RCT6, supports further expansion. It is ideal for starting application development with STM32F family.
-
Minimal ready-to-run system, integrates clock circuit, USB control circuit, USB connector, etc.
-
All the I/O ports are accessible on the pin headers
-
JTAG/SWD programming/debugging interface
-
2.54mm header pitch, allowed to be plugged-in your application board
