Product Details
Product Introduction:
This board adopts FM stereo transmit integrated BA1404 and 9018 radio frequency amplification circuit.
It has stable frequency,and operating voltage is 3V. It adopts frequency modulatoion stereo transmitting technique,
and it can transform stereo audio signal to frequency modulation stereo electric wave;and it can also achieve
stereo audio signal wireless high fidelity transmission.This board can be used as wireless microphone;
when plug into stereo audio signal as transmitter.Operating frequency is 85-115MHz continuous and adjustable,
its reference transmitting distance is 10-100m.
