Mini FM Transmitter Module Wireless Radio Microphone Module for Mini Bug Wiretap Feature : External dimensions of 20x20x10mm, module containing a microphone, high sensitivity to sound sensor, sound sensor sensitivity can also be controlled by an external resistor; internal oscillator source is a relatively reliable and efficient oscillation circuit, transmit power, transmit distance, Harmonic wave content of less extent small body sensors, use a soft wire as a transmission antenna, all-metal box shielding, smaller size, more stable performance, can replace MEC002A directly, it will adjust the external frequency power supply capacitors and filter circuit is also integrated into the module, the module main feature: 1, very wide adjustable operating frequency range of at least 85-115MHz. 2, very wide operating voltage range of 1.5-12V. 3, strong and efficient power FM transmitter, so that it can be directly driven by C1971 C RF power amplifier circuit constructed so that transmission range is incremented to three kilometers. Different operating voltages using reference 1 m flexible wire transmitter in the open fired at a distance of about 1.5V (30 ?), 3V (50 ?), 6V (100 ?), 9V (150 meters) and 12V (200 meters), supporting the use instructions. Module has five pins: + (power supply positive), - (power negative), ANT (antenna connection), AO (internal microphone audio output), AI (external audio modulation input), use only plug in the power and antenna In between AO and AI series a resistor (1-10K, this resistance can be controlled to change the sound of the microphone sensor sensitivity, there is supporting a 2.2K resistor) to work. 104-1uF need a capacitor connected in series to the AI-pin external audio signals package : 1pc module We accept PayPalonly.
