Features:

1: Use advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation technology (PLL) to make the sound quality more realistic, the performance is more stable, and there is no deviation in the long-term working frequency.

2: The LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference.

3: Built-in 30-level digital volume adjustment, easy to complete with key operation.

4: Automatically memorize the data before power failure

5: Automatic switching of multi-channel audio input

6: Use quartz crystal frequency stabilization, the temperature changes and the emission frequency no longer drifts

7: Support serial command control



Product parameters:

Output power: 100mW

Audio frequency response range: 50Hz-18KHz

Transmission frequency:

Turn off campus broadcasting 87.0MHz-108.0MHz, turn on campus broadcasting 76.0MHz-108.0MHz


Frequency adjustment step: 0.1MHz / time (short press of key), 1.0MHz / time (long press of key)

Modulation mode: standard FM frequency modulation

Channel: LINE / USB channel (stereo), MIC channel (mono)

Equivalent noise: ≥30dB (sound quality close to CD sound quality)

Power supply voltage: DC 3.0V-5.0V

Working current: 35mA

Transmitting antenna: 75cm whip antenna

Transmitting distance: The FM transmitting module is connected to a 75cm standard whip antenna, and the radio uses the Desheng PL-660. The measured radius of the open field is 100 meters. (Note: The launch distance is for reference only, slightly different due to different environments)


Precautions:

1: The power supply voltage must not exceed the power supply voltage range of this module.

2: Do not touch the back components of the module during operation, so as not to affect the normal operation of this module or cause a short circuit to burn the module.

Note:
Due to manual measurement, please allow 1-3mm different.
Due to different displays and different lighting, the image may not reflect the actual colors of the project. 
Thank you for your understanding.

When purchasing electronic components, please have certain electronic basic knowledge of the module. Most modules only provide descriptions or send materials. There is no technical consulting support. Please be careful to shoot for beginners.
