[HI-12F] Development board based on the Ai-Thinker hi-12f module

Overview

This development board, based on the Anxinke hi-12f module, integrates two buttons, a tri-color LED, and a sliding rheostat. It can connect to an external 0.96-inch LCD screen. ( The tutorial in
the CSDN blog post
"Hi3861 OpenHarmony Embedded Application Introduction - HarmonyOS Development Environment Setup"
will be gradually improved.)

Summer mini fan

Speed-adjusting fan based on FM5012D chip

This product uses the FM5012D as the main control chip. This chip has two LED driver ports; the button port can simultaneously drive LEDs as a status indicator for the fan being on, and the LEDR port drives an LED indicating the charging status. The FM5012D features multiple protection designs, including overcurrent protection, soft-start protection, input overvoltage protection, output short-circuit protection, and chip temperature protection. The chip ports also incorporate high-performance ESD protection circuitry, giving this chip extremely high reliability. It features three fan speed settings and uses a standard coreless motor, making it simple to manufacture.
