STM32F103C8T6 ARM STM32 for minimum system development board module
This is a core chip based on STM32F103C8T6ARM core board. The functions are as follows:
1. The motherboard is based on the most basic MCU circuit, 8M and 32768 crystal oscillator circuit, and USB power supply circuit.
2. The core board is divided into two lines, leading to all I/O ports.
3, SWD simulation debugging download interface, simple and convenient, fast debugging.
4. Using Mirco USB interface, can do USB communication and power supply, USB interface, compatible with common android phone charger interface.
6, RTC crystal epson brand, easy to start, more stable.
7. With double stitches, but no default welding of stitches, users can choose the welding direction suitable for themselves according to their own application scenarios.
