Brief Introduction: The main control chip is composed of STC89C52 chip and TDA5807 core device, it is connected through the I2C bus between the master and slave devices, and the TDA5807 chip is driven to work by software simulation of bus timing, the program automatically searches for radio stations, with a frequency reception range of 87 to 108MHZ, the frequency band information is displayed in real time on the LCD1602 LCD screen. The output audio signal is amplified and processed through the power amplifier chip LM386, which drives the speaker to work. Effectively reducing noise interference while listening to the radio, and with the help of the power amplifier chip, the sound becomes clear, with level indicator, makes listening to radio stations a pleasure. Product Features: 1. This module adopts a DC 5V working voltage, which is easy to access and supports computer USB power supply and mobile charging bank. 2. This audio receiver adopts digital tuning and quantity volume control. It is more convenient to search for radio stations and adjust the volume..
