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.
