FM Radio Adjustable Frequency Meter DIY Electronic Kit 87-108MHZMHz BK4802P+RDA5807 Chip – 1 set

説明

特徴：

1. Combines walkie-talkie and radio functions into one, allowing for both intercom and FM radio reception.

2. Utilizes the BK4802P RF + RDA5807 dual-chip radio for strong signal quality, noise reduction, and interference resistance.

3. Onboard 0.96-inch OLED screen for clearer display.

4. Smart intercom radio kit, offering both intercom and FM radio with crystal-clear sound quality.

5. SMD components pre-soldered; only some plug-in components need to be soldered, perfect for hands-on practice.

 

製品説明：

The smart intercom radio kit combines the functions of a walkie-talkie and a radio, meeting your dual needs for wireless communication and radio listening. Two intercoms form a pair; a single unit can function as a radio, not for intercom use. We recommend purchasing a pair. The RF transceiver chip ensures clear voice intelligibility. The intercom operates in the 409.85MHz frequency band, with a range of approximately 200 meters, meeting communication needs in a variety of scenarios. Equipped with 87-108MHz radio frequency band, it offers low noise, strong anti-interference capabilities, automatic radio station search and storage, and easy operation.

 

The SMD components are already soldered, requiring only the plug-in components for a high assembly success rate. Suitable for radio enthusiasts, electronics hobbyists, and those engaged in skills training to enhance comprehensive practical skills.
