TDA7297 Audio Amplifier Board 12V Stereo Amplifier 2 Channel Ble Power Amp Wireless Audio Receiving Module Decoding
Product Description
TDA7297 is a classic 2.0 power amplifier chip, well known for its excellent performance and high fidelity and high power output. In response to market demand, we use this chip to add a mini BLE module to combine it into a smaller BLE power amplifier. When you get it, you can turn on the power supply and the speaker and immediately produce sound. With BLE audio, you can get rid of the wire bondage. The BLE module is specially designed to receive pure audio during programming, without functions such as call and radio. Incoming calls are answered directly with the mobile phone to avoid interference with others and effectively protect your call privacy. After the call, it will continue to automatically play music.
