CI1122 offline voice remote control

The Qiyingtailun CI-C22GS02S offline voice module is used here, and a development baseboard is made by myself. Then based on this, a wireless voice remote control transmitted through a 2.4G wireless serial port module was produced. It is mainly used to test remote control of the car through voice.
The circuit is very simple, mainly 3.3V voltage stabilizing circuit, CI-C22GS02S module development board, and LC12S wireless serial port module.
Main principles:
1. Transmitter: The serial port 1 of the CI-C22GS02S module is connected to the LC12S. The data from the serial port 1 of the CI-C22GS02S module is sent out through the LC12S wireless serial port module. It can also receive voice control commands sent back remotely.
2. Receiver: An ARDUINO NANO expansion board is used, and an LC12S wireless serial port module is connected to the serial port to receive the data sent by the voice module. ARDUINO NANO analyzes the data after receiving it, and then performs corresponding actions according to the parsed command.
The first version was not designed with battery power in mind, which resulted in the need for an external power bank every time it was used.
 
Follow-up: The actual test voice remote control is suitable for some scenarios with relatively low real-time requirements and is not suitable for car control because there is a certain delay and sometimes voice recognition errors occur.
