Micro FM wireless microphone FM transmitter module FM transmitter FM wireless broadcast wireless

Product features:

1. On-board built-in microphone2. The sensitivity of input microphone and audio is adjustable, and the transmitting frequency is continuously adjustable,3. Transmitting power: 5V input can reach 150MW transmitting power, and the open space is over 300 meters.4. All ed components, work stably, frequency does not drift, hand touch does not drift.5. Broadband modulation, excellent sound quality, comparable to FM radio station sound quality.

Product parameters:

[Dimensions]]Length 2cm * width 1cm * thickne 0.48cm

[Operating voltage]]DC 2V--12V (Type A)(It is recommended to supply use a battery power, the regulated power supply will have AC sound, and the voltage rise frequency will change slightly, but the long-term working frequency will remain unchanged under the power supply of the same group of batteries)

[Work current]]9mA(3V voltage test, super power saving, voltage rise-> Current increase-> power plus-sized> distance longer,)

[Transmitting distance]]The open ground is 100 meters (3V voltage test), the indoor wall-through distance decreases, and the reinforced concrete wall distance decreases obviously, increasing the voltage can greatly increase the distance.

[Working frequency]]85MHz -- 115MHz (the default factory frequency is generally between 99.0 and 100.9 MHz)

[Receiving method]]Ordinary FM FM radio can be received, and mobile phones with FM function can also be received. Our store also has two receiving (FM radio) modules. app radios that use network data traffic cannot be received.

[Frequency adjustment]]Miniature Variable capacitor on the circuit board, with small screwdriver twist to adjust the frequency

[Output impedance]]50

[Sensitivity]]The microphone is placed in a quiet 15 square meter room, and the sound of quartz clock seconds is clear and audible.

[Usage]]High sensitivity wirele microphone, wirele recording, wirele monitoring, e recording, maternal and child care, patient care, etc. Because the sensitivity is too high, it is not suitable for stage performance, and it is easy to produce howling sound.Do not use it for illegal eavesdropping! At your own risk!

[Working hours]]The working time of the module is determined by the battery capacity. The specific time use A battery capacity divided by module work current, our store A/B/C/E/F five modules work current are different, the page has A introduction. For example, if work current of Model A is 9ma at 3v, the working time of using A 3.7v,900mAh lithium battery is: 900 divided by 9=100 hours.
