2018 Electronic Competition Question F-Wireless Microphone Amplification System (Dalian University of Technology)

Outstanding works of e-sports competition in 2018

Overview

This design is an ultra-low power consumption 16-bit microcontroller msp430f5529 designed and produced by TI as the main control chip, supplemented by necessary circuits. The FM transmitter based on RDA5820 can transmit 88MHZ~108MHZ FM signals, and RDA5820 can detect When the signal is occupied, the carrier frequency is automatically selected to avoid interfering signals. The OLED display is used as the display module to display the transmission frequency, signal strength and other information. The receiver uses a finished radio wireless receiving module, uses a TDA2030 power amplifier to amplify the signal, and uses a speaker to broadcast it. Finally, an FM transceiver with high sensitivity and low anti-interference ability was completed.
