Stereo Wireless Speaker Bluetooth 4.0 Audio Receiver Module For DIY Modified Speaker
This module stereo output, built-in Bluetooth antenna structure is simple, the power supply voltage for 5V power supply can be used as a common power amplifier, active speaker to increase Bluetooth connection function.7PIN output interface is 2.54 through-hole spacing, 7PIN output interface is: + power supply, grounding, left channel, right channel, mute, LED status indication, reserved interface. Where the LED status port is connected with a series of 100-ohm resistors, the LED indicator is connected to the ground. When the Bluetooth is not connected, it is a flash, and when the Bluetooth connection is successful, it is a slow flash.
(5V) power supply: connect to the positive pole of the power supply, and the voltage range is 4.2v-5v. Please ensure that the power supply is within this range. Exceeding this range may damage the module or cause abnormal operation (GND) ground: GND is connected to the negative pole of the power supply.
(L) left channel: connect the left channel input of the power amplifier board, or the left channel of the headset. It is suggested to connect a capacitor at the output port (depending on the input matched by the power amplifier).
(R) right channel: connect the right channel output of the power amplifier board or the right channel of the headset. It is suggested to connect a capacitor at the output port (depending on the input matched by the power amplifier).
The port is preset to a high level and when MUTE the port outputs a low level (LED) status indicator: when the Bluetooth is not connected, the light flashes quickly, and the light turns to slow flash after the Bluetooth connection is successful Reserved port: the port has been pulled up to 5V. Featured by Sharvi Electronics When the port is triggered by a low level, it will be shut down. When another low level is given to the port, it will be turned on
Note: The capacitor component may vary in terms of voltage range & capacitance w.r.t. the one which is shown in the image above.
