DSP PLL LCD Display FM Receiver Module (87-108MHZ) Digital Wireless Microphone Stereo Input

DSP PLL LCD Display FM Receiver Module (87-108MHZ) digital wirele microphone stereo Input

describe:

100% and high quality

Material: electrical components

Color: see ture

Product parameters:

1. Output power: 100mW

2. Audio frequency response range: 50Hz-18KHz

3. Transmiion frequency:

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

4. Frequency adjustment step: 0.1MHz/time (short key pre), 1.0MHz/time (long key pre)

5. Modulation mode: standard FM frequency modulation

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

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

8.Supply voltage: DC 3.0V-5.0V

9. Working current: 35mA

10. Transmitting antenna: 75cm wh antenna

11. Transmitting distance: The FM module is connected to a 75cm standard wh antenna, and the radio uses Tecsun PL-660. The measured coverage radius of the open area is 100 meters. (Note: The launch distance is for reference only, and it may vary slightly due to different usage environments)

Features:

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

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

3: Built-in 30-level digital volume adjustment, key operation can be easily completed.

4: Power off automatically memorize the volume and frequency information before power off

5: Multi-channel audio input automatic switching

6: High-precision ch quartz crystal is used to stabilize the frequency, and the emiion frequency will no longer drift when the temperature and voltage change

7: Support serial port command control

The package includes: 1x PLL LCD digital FM module 87-108MHZ wirele microphone stereo

Use introduction:

power supply :

1. The module has a Micro USB interface and can be powered by a computer USB.

2. The corresponding ports of the module (marked on the )-and + are respectively connected to the negative and positive terminals of the power supply (battery). It is recommended to use a battery or other regulated power supply for the power supply. It is not recommended to use switching power supplies without filters (such as mobile phone chargers, mobile power supplies, and other switching power supplies), otherwise the interference generated by the power supply will affect the normal operation of this module. The normal working voltage of this module is 3.0-5.0V, and the power supply voltage should not exceed this range.

Antenna:

The FM_ANT port is used to connect an FM antenna. In order to better receive FM signals, it is recommended to connect a 75cm-long wh antenna.

To

Line input: You can use the 3.5mm standard audio plug to input the stereo sound signal. If no plug is inserted, the microphone signal will be automatically ked up (the microphone signal is on the left channel). USB audio signal input is also available.

Volume adjustment: Pre VOL— or VOL+ to adjust the volume, and the LCD screen displays the volume level.

Frequency adjustment: Pre VOL- or VOL+ to adjust the transmiion frequency, short pre +-0.1MHz, long pre +-1MHz, and the LCD screen displays the current frequency

Mute: Short pre the PAUSE on down to switch mute/non-mute

Connect to the serial port (no need for serial port control): The module reserves a TTL level serial port control interface. The communication between the TTL serial port and this module needs to be connected to the module's UART_RX, UART_TX and GND (the corresponding position on the is marked), and an external MCU ( Single-ch microcomputer) or the computer serial port sends instructions to control the relevant functions of the module. For specific serial port commands, please refer to the doent "FM Transmit AT Command List"
