Hifi 5.1 Stereo Audio Bluttooth AC6965A Receiver Module For DIY Amplifer With Audio Signal Input Function Wireless Music Board

Features: 1. Adopting TD5161A stereo BT receiver chip, it has functions of audio BT reception and audio signal input. 2. Strong audio decoding ability, compatible with multiple formats of audio, meeting high-quality playback requirements. 3. Adopting BT 5.1 technology to ensure more stable wireless connection, longer transmission distance, and low power consumption performance. 4. Low power design, optimized design can more flexibly adapt to application scenarios. 5. Widely applicable, suitable for various products such as BT speakers, smart speakers, BT headphones, etc.Parameter: 1. Adopting TD5161A stereo BT receiver chip, it has functions of audio BT reception and audio signal input. 2. If it is only used for BT reception, only power supply and audio output are needed, and other interfaces do not need to worry about it. 3. If audio input function is required: Audio input control - K needs to be connected to GND, which can be achieved by connecting a self-locking switch or a headphone jack with a switch pin. (Note: The audio input function only works when switched on when powered on. If powered off and turned on again, the audio input control switch needs to be switched once. Otherwise, the BT receiving function will still be used by default.) 4. The reserved MUDE function switching interface is invalid for use on this board (to be developed) 5. Equipped with microphone interface MIC-IN (microphone needs to be provided), connecting the microphone can achieve BT calling function. 6. The M interface is a mute control interface that outputs a control voltage of around 3.3V when the playback is paused or there is no signal output. In the playback state, the voltage of this interface is 0V. This interface can be connected to an amplifier board with a mute interface for use. 7. All button functions (P/P, VOL -, VOL+) are triggered to ground (GND) (the board does not have buttons and can be connected separately). Product parameters: Module working voltage: DC3V-5V (try to use high-quality power supplies to avoid noise generation) Connect your phone to this BT module and it will display TD161A.
