Key benefits Simple, reliable power amplification: The power amplifier section uses the TDA2822 IC, delivering a simple circuit with good sound quality across a wide operating voltage range. Global FM reception with strong RF performance: The main control uses the STC15W microcontroller paired with the RDA5807S FM module, covering the global FM band of 87108 MHz with sensitivity, low noise, and strong antiinterference performance. Features include noise suppression and soft mute for clear listening. Educational and handson ready: as a parts kit, it is designed for soldering practice and learning by building a real radio from scratch. Clear display and convenient connections: Digital tube display provides easytoread status, and a headset/phone connection enables private listening. What it is and how it works Core components: Power amplification with TDA2822, main control with STC15W MCU, and FM receiving via the RDA5807S module.
