Super mini offline voice control switch

Overview

* 1. Introduction to project functions

A super mini offline voice control switch based on the CI-C22GS02S module of Qiyingtailun. The development board is designed to use 12V power supply. The 12V power supply powers the electric fan and uses 12V-5V step-down to power the offline voice module; PWM4 is reserved. , PWM5 interface is convenient for subsequent development, and the microphone and speaker interfaces are also drawn out, which can be used by direct wiring. The demonstration video can be viewed in the attachment. The firmware is also uploaded in the attachment.

*2. Project attributes

The project was made public for the first time, learning production at Lichuang EDA Summer Training Camp

* 3. Open source agreement
