Description
The module has an integrated Bluetooth antenna with stereo output. The voltage of the power supply is 5 V. It can be used as a common power amplifier and active speaker to increase the Bluetooth connection function. Output interface PIN 7 to space the hole 2.54, 7PIN output interface for: + power, ground, left, right, silence, LED status indication, reserved port. Among them, the LED status port is connected to a 100 ohm resistor in series. The LED indicates that the Bluetooth is not connected and that the flash is fast. After the Bluetooth connection is successful, it blinks slowly. Plate size: 30mm X 20mm X 3mm Operating voltage range: 4.1 V-5 V (not more than 5.1 V, when using charger power supply, power supply Charging the car or DC-DC power supply, pay attention to the voltage of the power supply and the ripple voltage, you can tie a diode Working current: 30-50mA
