Typical Applications for the TDA7492P Wireless Bluetooth Digital Amplifier Board:

The TDA7492P Wireless Bluetooth Digital Amplifier Board is a great board to use for almost any basic audio application, and is very often utilised to build custom sound systems. With the option for both standard stereo audio input, as well as input via Bluetooth, it is ideal for using as a vehicle sound system controller, as it can play your music directly from your phone, while offering the choice to answer phone calls as well. Building a custom sound system for a car dashboard with this board also allows anyone in the car to become the DJ and play music from their phones, which is a great feature if you often have friends or family with you while driving.

Finally, if you're still a little bit unsure about this module, and would like to see an example of it working out in the wild, check out this awesome TDA7492P Project Guide from Kavi's Blog, done by a passionate local Maker who doesn't like waiting for tech't to arrive, but instead takes the initiative and create the tech' he wants. In this guide, he revitalies some old-school speakers with this TDA7492P Amp Module, while offering some handy insights to help fellow Makers get the most out of these humble but powerful boards. This of course is just one idea (and a really good one at that!) but if you have other plans on how to use these amplifiers boards, be sure to share your success and we will share it with the community, because this is what Open Source Making is all about: Learning, Sharing, Helping and Succeeding together.



Good sound

Very nice board. It doesn't have the loud poping sound when starting/stopping playback like some of the cheap bluetooth modules. It also only plays a melody on start-up and not every time a device connects/disconnects, which I think is great.
