FM Frequency Modulation Receiver

1. Introduction

This FM stereo digital radio circuit board module has built-in DSP

digital noise processing. When there is no signal, it will automatically

mute and get rid of the noise of the traditional FM radio.

2. Parameter

NO.

3. Using attention:

1>. The power supply voltage is strictly prohibited to exceed the

power supply voltage range of this module.

2>. Do not touch the back part of the module when working, so as

not to affect the normal work of this module or cause the short-circuit

burn module.

Advanced digital audio signal processing technology (DSP) and FM phase-locked loop modulation (PLL) make the sound quality more realistic, more stable performance, and long working frequency without deviation. 2>. LCD display is more intuitive and accurate, with extremely low power consumption and minimal noise interference. 3>. 30 digital volume adjustment, with buttons, easy to operate. 4>. Automatically storage data before power off. 5>.

The power supply is recommended for battery or other stabilized power supply.You cannot use a power supply without filter (such as mobile phone charger, mobile power supply, and other switching power supply), otherwise the interference caused by power supply will affect the normal work of this module. The normal working voltage of this module is 3.0-5.

Frequency regulation Turn the FRE encoder to adjust the reception frequency, while the LCD screen displays the current frequency, and press the encoder handle to the mute/non-mute switch. 6>. Mute Press the VOL knob to switch the mute/non-mute button down. 7>. AMCAP switch Long press the FRE knob to switch on or off the AMCAP, the LCD display subtitle ON means to turn on the AMCAP, and OFF means to turn off the AMCAP. 8>.

Note: because the computer serial port is not TTL level, connect the computer communication, it is necessary to connect the RS323 level to TTL power leveling device or the USB TTL level serial port module to communicate with this module. This operation requires professionals. 10>. User Settings This module can set the backlight state according to the user's specific usage.
