DIY Walkie Talkie FM Radio Electronic Kit Adjustable Frequency 87-108MHz Digital Display DIY Soldering Project Practice RDA5807

Features: 1. The intercom and radio functions are integrated into one, capable of intercom and FM radio reception. 2. Adopting BK4802P RF RDA5807 dual chip for strong signal noise reduction and anti-interference. 3. Equipped with a 0.96-inch OLED screen, the display content is clearer. 4. Intelligent intercom radio kit, intercom call/FM FM radio/clear sound quality. 5. The surface mount components have been soldered, only a portion of the direct insertion components need to be soldered to improve manual dexterity.   Product Introduction: Intelligent intercom radio kit, integrating intercom and radio functions, can meet your dual needs for wireless communication and radio listening. Two sets of intercoms form a pair, each can be used as a radio but cannot be used for intercom. It is recommended to buy a pair. Using RF transceiver chips, the voice is clear and distinguishable. The walkie talkie operates in the 409.85MHz frequency band and has a communication distance of about 200 meters, which can meet communication needs in various scenarios. Equipped with a radio function in the 87-108MHz frequency band, it has low noise, strong anti-interference ability, automatic search and storage of radio stations, and easy operation. The surface mount component has been soldered, only the direct insertion component part needs to be soldered, and the assembly success rate is high. Suitable for radio enthusiasts, electronics enthusiasts, and skill teaching and training, enhancing comprehensive practical abilities.
