The board is a double-layer board, with most components in 0603 surface mount packages, making it suitable for beginners who want to learn soldering. The XT-30 module in the lower left corner can be removed if the 12V requirement is not needed. It can implement everyday functions such as a buzzer, LED, digital display, and buttons. All pins are brought out for various expansion capabilities. The board uses SWD/USB download and supports 5V/3.3V/12V power supply, making it easy for beginners to learn.
