How to Use:
Wiring Method: 
The back of the core board is marked with +,‑and ANT, which represent the positive pole, negative pole and antenna end of the power supply respectively. The antenna is generally welded with a 0.7‑meter‑long short wire.

Specification:
Item Type: Audio Transmitter Module
Material: PCB
Application: Widely used in sound transmission pickups, audio microphones, sleep monitoring of the elderly and children, etc. where sound needs to be captured
Working Voltage: Ultra-wide 0.7V-9V
Frequency Adjustment Range: Wider than 88-108MHZ
Transmission Distance: When working at 9V, use 70cm wire as antenna, and the transmission distance is approx. 50-100meters / 164-328.1ft in an open area, depending on the actual environment
The relationship between working voltage (volt) and supply current (milliamps) and emission power (dBm) is as follows:
Working Voltage Supply Current Transmit Power 9V 24mA 10.2 dBm (about 11mW) 8V 21mA 9.5dBm 7V 19mA 8.5dBm 6V 17mA 7.1dBm 5V 14mA 6.1 dBm (about 5mW) 4V 12mA 4.5dBm 3V 9mA 2.2dBm 2V 6mA -1dBm (about 1mW) 1.5V 4.2mA -4dBm (approximately 0.5mW, emission in general home environment) 1V 2.4mA -9dBm 0.7V 0.9mA -20dBm (about 0.01mW)

Package List:
