Ai-Thinker VC offline voice control

 
Overview
Anxinke Technology's new offline voice module has been put on the shelves two days ago. At the same time, a board for controlling the relay was drawn to demonstrate the voice recognition and control functions of the VC02 module.

Control principle

The control principle is very simple. It uses relays to control 220V lights.

Schematic diagram

The schematic is not particularly complex, it can even be said to be very simple, because the module integrates a power amplifier chip, so the audio processing circuits for the microphone and speaker can be omitted.

PCB

The shape of the PCB is designed with reference to the housing of the LED controller for safety.
