8051 development board (STC32G12K128)
8051 Development Board Overview
The 8051 development board (STC32G12K128) is a cost-effective STC32 development platform for beginners. Its main control chip is STC32G12K128. It has on-board resources commonly used for learning microcontrollers (including download circuits, user buttons, and user LEDs). The interface of commonly used sensors is also onboard, which can be connected to many commonly used sensors. Users can also expand more applications through the derived IO.
Function and positioning:
•Learn microcontroller hardware circuit design.
•Learn to program microcontrollers in C language, including peripherals, sensors and wireless communication modules.
•Learn the development of IoT-related applications.
