FM Radio Kit SYJ-1 with Front Acrylic Cover RDA5807M and PAM8403 Chips 87–108 MHz LED Display Power Supply 5 V USB-C Soldering Practice
You already have the maximum available quantity in your cart.
The FM radio soldering kit SYJ-1 with a front cover allows you to build your own desktop receiver that looks like a finished product once assembled. The electronics are enclosed between two acrylic panels, the front of which has openings for the speaker while also protecting the mounted board. The radio receives broadcasts in the 87–108 MHz band and automatically searches for stations. The radio chip RDA5807M, microcontroller STM8S003F3P6, and 32.768 kHz crystal are pre-soldered on the board from the factory, as their soldering is challenging. You will solder the other components by hand, allowing you to practice working with a soldering iron.
The sound is managed by the integrated amplifier PAM8403 with a simple configuration, good sound quality, and a wide operating voltage range. Control is provided by four buttons: FRE+ and FRE- automatically search for stations up and down, VOL+ and VOL- adjust the volume. On the front, you will find a four-digit LED display, a power switch, and a power indicator. The receiver offers noise suppression, soft mute function, bass enhancement, high sensitivity, and good resistance to interference. The entire assembly is held together by brass spacers and screws.

The number of stations the radio can tune in depends on the signal strength at the location of use. Other electronics nearby may interfere with reception, so place the radio away from them. With a weak power source, the radio may restart at high volume, so use a 5 V adapter with sufficient current. We also recommend soldering the antenna after screwing it in and securing the speaker with a foam pad.
This kit is suitable for electronics clubs, school workshops, and home DIY enthusiasts who want to see how a modern FM receiver works. The transparent covers keep the soldered components visible. You can place the finished radio with the LED display on your desk and listen to your favourite stations. It can be powered via the included cable or through the USB-C connector. The kit is also a good choice as a gift for budding electronics enthusiasts.
