Key Features

Features:

[ACCURATE FREQUENCY FINDING] - The FM transmitter pickup module uses a manual knob to find the station more accurately. Input the receiving frequency carefully, such as 88.1MHZ, 88.2MHZ, 88.3MHZ, etc.
[LONG TRANSMITTING RANGE] - With a 9V power supply and a 0.7m/2.3ft wire antenna, this FM emission mic core board can transmit up to 50-100m/164.0-328.1ft in open places. Actual distance may vary depending on the environment and receiver sensitivity.
[WALL PENETRATION] - The FM transmitter pickup board is capable of penetrating , allowing through 2-3 blocks depending on the wall structure and density. The wall penetration capacity is influenced by antenna placement, battery voltage, and radio sensitivity.
[BATTERY POWER SUPPLY] - This FM transmitter pickup module can be powered by common batteries. The higher the working voltage, the greater the transmitting distance. Working time depends on battery capacity. Actual working time may vary.
[PREMIUM MATERIALS] - Made from high-density PCB material, this FM radio transmitter module is , reliable, and to aging. It operates on a wide voltage range of 0.7V to 9V and offers a wider frequency adjustment range of 88-108MHZ.

Description

Spec:

Item Type: FM Transmitter Pickup Module

Material: PCB

Operating Voltage: Ultra Wide 0.7V to 9V

Frequency Adjustment Range: Wider Than 88-108MHZ

Transmitting Distance: 9V Work, Using 70cm/27.6in Wire for Antenna, Open Place Transmitting Distance of 50‑100m/ 164.0‑328.1ft, The Actual Depends on the Environment

The Relationship Between Operating Voltage (Volts) and Supply Current (mA) and Transmitting Power (dBm) is as Follows:

9V, 24 mA, 10.2 dBm (That is, 11 mW)

8V, 21 mA, 9.5 dBm

7V, 19 mA, 8.5 dBm

6V, 17 mA, 7.1 dBm

5V, 14 mA, 6.1 dBm (Approximately 5 mW)

4V, 12 mA, 4.5dBm

3V, 9 mA, 2.2dBm

2V, 6 mA, -1dBm (~1 mW)

1.5V, 4.2 mA, -4 dBm (About 0.5 milliwatts, the general home environment is enough to transmit, green radiation is small!)

1V, 2.4 mA, -9 dBm

0.7V, 0.9 mA, -20 dBm (That is, 0.01 milliwatts)

Package List:

1 x FM Transmitter Pickup Module

How To Use:

Wiring method:The back of the core board is marked with +, ‑, and ANT, representing the positive power supply, negative and antenna terminal, the antenna is generally soldered a short 0.7 meters long wire can.

Note:

It is not recommended to use the earphone wire as the receiving antenna for the mobile phone, which has low sensitivity and large interference, and the effect is affected.
