You already have the maximum available quantity in your cart.
This digital FM radio kit is designed for anyone who wants to learn to solder and understand how a modern radio receiver works. Once assembled, it picks up stations in the 87 to 108 MHz range and plays them in stereo through standard headphones. The heart of the circuit is the radio chip RDA5807, which handles reception and automatic station searching. The current frequency and other information are displayed on a four-digit LED display. The kit is suitable for electronics education in schools, clubs, and for independent hobbyists.
All components are inserted into holes on the printed circuit board, making it manageable even for beginners with a basic soldering iron. The board measures 60 x 32 mm and features printed component markings and button labels, which aid in orientation during assembly. Control is managed by five buttons for power, tuning, and volume. Power is supplied by two AA batteries in the included holder with wires.

Once powered on, simply hold the power button for about two seconds, and the radio will scan the entire band, storing found stations in memory. Use the PR- and PR+ buttons to change the frequency, and holding them will tune quickly, stopping at the nearest station. The V- and V+ buttons adjust the volume. If the radio is not operated for 59 minutes, it will turn off automatically to save battery. For the best reception, we recommend listening from a higher floor or in an open area.
The FM stereo radio kit with the RDA5807 chip offers meaningful work with a soldering iron, resulting in a functional receiver for headphone listening. You will learn to identify and correctly place resistors, capacitors, coils, crystals, and integrated circuits. The finished radio with automatic station searching and memory for 64 presets will delight any young electronics enthusiast. The kit can be used as a teaching aid in physics and technology lessons or as a fun weekend project. Batteries and headphones are not included.
