Recordable Sound Module
The recording module is an electronic device that records sound signals on media and plays them back. It usually consists of recording circuit, playback circuit, memory and control circuit. Common recording media include records and tapes, and mobile phones also have recording functions. Through the microphone of the recording module, the sound can be recorded for a certain period of time, and the recorded sound can be played back through the speaker.

Overview
The recording module is divided into two types: ICC communication recording and key recording. A single recording chip can store content for 70 seconds. In addition, the recording chip is paired with flash and TF cards to store the recording content. Trigger method: ICC communication can be used for recording and playback through the microcontroller. Key-press recording starts recording after being triggered by a key. Press the key again to stop recording. Set other keys to play the recording.

Guide
If the standard functions of the module cannot meet the needs of customers, the module can be developed to customize some functions. If you need to develop customized functions, you need to list the required functions first, and then send them to our technical consultation for evaluation. After the evaluation is passed, an engineer will contact the customer to develop the corresponding function. Some common functions are listed below.
1. Increase the number of recording segments and the corresponding button functions, such as adding 5 recordings, button for the next song, etc.
2. Change the default control mode when power on, for example, when the module is powered on, it will start to play the recorded files in a large loop.
