This project is an STM32F103C8T6 microcontroller development board with SW, TypeC interface (using USB2.0 protocol), and dual-row GPIO interface (one GPIO interface corresponds to pin header x1 and female header x1). And it has a DIY interface, which can be customized through jumpers. This development board contains ULN2003A, which can be programmed to directly drive inductive loads such as motors with an external power supply. It also has a pair of crimping terminals to facilitate the use of batteries and other power supplies. It also contains CH340G, which can perform data communication and power supply through the onboard TypeC interface.
