Product Features:
1. Combines walkie-talkie and radio functions into one device, enabling both walkie-talkie communication and FM radio reception.
2. Utilizes the BK4802P RF + RDA5807 radio dual-chip solution for strong signal strength, noise reduction, and interference resistance.
3. Features a built-in 0.96-inch OLED display for clearer content display.
4. Smart walkie-talkie radio kit offering walkie-talkie communication, FM radio reception, and clear audio quality.
5. Surface-mount components are pre-soldered; only some through-hole components require soldering, providing an opportunity to practice hands-on skills.

Product Description:
The smart walkie-talkie radio kit combines walkie-talkie and radio functions, meeting your dual needs for wireless communication and radio listening. Two walkie-talkie units form a pair; a single unit can be used as a radio but cannot function as a walkie-talkie. It is recommended to purchase a pair. Utilizing RF transceiver chips for clear and distinguishable voice quality, the walkie-talkie operates on the 409.85MHz frequency band with a communication range of approximately 200 meters, suitable for various communication scenarios. Equipped with an 87-108MHz frequency band radio function, it features low noise, strong anti-interference capability, automatic station search and storage, and user-friendly operation.
Surface-mount components are pre-soldered; only through-hole components require soldering, ensuring high assembly success rates. Suitable for radio enthusiasts, electronics hobbyists, and skill training, enhancing comprehensive practical skills.
