87-108MHz FM Radio Walkie-Talkie DIY Kit for Electronic Assembly And Soldering Practice with Micro USB Interface

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.Parameter: Kit Name: Interphone Radio Electronic DIY Kit Maximum operating current: approximately 200mA (with the sound set to maximum) Power supply method: Three AAA batteries or 5V USB power supply (both cannot be used simultaneously) PCB length: 95.5x61mm Dual function: walkie talkie+radio dual-mode 1、 Interphone function: 1. When there is no operation, it will automatically detect and receive signals 2. Press the 'intercom' button to initiate a voice conversation 3. Press the "Call" button, and the receiver's walkie talkie will ring 4. Can view intercom signal strength 5. The walkie talkie operates in the 409.85MHz frequency band 6. The communication distance of the walkie talkie is about 200 meters 2、 Radio function: 1. When the radio does not have a stored radio station, it will automatically search for surrounding radio stations and store them (up to 30 radio stations can be stored, any more cannot be stored) 2. 15 sound levels, adjustable sound freely 3. Equipped with power-off memory, automatic channel search and storage function, and list management of radio stations 4. Equipped with sleep mode, making the whole machine more energy-efficient 5. Radio receiving frequency band: 87-108MHz 6. Modify the search channel threshold 7. Can view radio signal strength characteristic: 1. Paired with OLED screen, the functional display is clearer 2. Paired with RDA5807 radio chip, it has the advantages of noise cancellation, bass enhancement, high sensitivity, low noise, and strong anti-interference ability 3. Paired with the BK4802P RF transceiver chip, it has core advantages such as excellent noise cancellation capability, strong audio processing performance, wide frequency band coverage, and outstanding anti-interference ability.Package Include: 1X Radio Electronic DIY KitNote: DIY of individual parts requires self welding and assembly to enhance hands-on skills. Self provided welding tools are required for welding, along with detailed installation tutorials.
