100% Brand New and High Quality

 
Dimensions: Length 1.8 cm * width 0.65cm

Operating Voltage: DC 2V-12V (recommended batteries, power supply will hum, Product middle pin as the anode)

Working current: 12ma (4.2V voltage test, super power)

Reference distance: 120 meters open ground, indoor environmental obstructions 10-30 meters (4.2v voltage test and improve the voltage distance greatly improved)

Operating frequency: 80MHZ --- 115MHZ (power-on default frequency is generally about 80Mhz)

Receive mode: as long as the FM radio 88-108MHz can receive, with FM feature phones can.

Frequency adjustment: change the inductance of the coil shocks that change the density, while poke frequency rises, when folded frequency decreases

Output Impedance: 50 Ohm

Scope: high sensitivity wireless microphone, wireless audio, wireless monitoring, maternal and child care, patient care.

This module is the latest micro SMD FM transmitter module, using good PCB fabrication, compact, easy to load crude pen barrel, within lighters. This module emits a fairly stable frequency can use any radio receiver, particularly the use of digital radio, the better. All components are using the brand devices.

Module supply voltage at 3V, firing distance of about 100 meters in an open environment, under normal indoor environments distance of about 20 meters, the higher the voltage transmitter farther away, firing range of up to about 300 meters when 9V voltage, the antenna can ordinary wire antenna length of about 75 cm, must be straightened when used, has been tested using a whip antenna works best! Of course, of course, the antenna can also emit shorter distance will be shortened firing distance measured only as a reference to the specific proposal.

Package Included:
1x Mini FM Transmitter Module
