STC32G12K128-LQFP48

Overview

STC32G12K128-LQFP48 is the smallest system core board. The power supply adopts TYPE-C. It is also designed with 3 LED lights, a power indicator light, single-lead ADC/VREF+, and all pins are led out in the form of pin headers. The 2P pin header is a power switch and does not need to be short-circuited directly.
