Mini FM Wireless Microphone Transmitter Spy Bug Module Single Channel Board 3-5V 100mW Adjustable Sensitivity USB to TTL 80KΩ 76-108MHz

Features: 1. Use advanced FM phase-locked loop modulation technology (PLL) to make the sound quality more realistic, more stable performance, and no shift in long-term operating frequency. 2. The audio dedicated low noise operational amplifier is used as the preamplifier of the microphone, with very low power consumption and minimal noise interference. 3. Power failure automatically remembers the frequency before power off 4. Using high-precision patch quartz crystal frequency stabilization, temperature, voltage change, the transmission frequency no longer drifts 5. The computer side configures the transmission frequency through the serial port, the frequency output is accurate, and the adjustable range is wide. Product parameters: Output power: 100mW Audio frequency response range: 50Hz-18KHz Transmitting frequency: permitted by the FCC 76.0MHz-108.0MHz (configure the transmitting frequency through the computer host computer) Modulation mode: standard FM Channel: mono Supply voltage:
