Overview
FM Radio Construction Kit for Soldering RDA5807 with Four-Digit LED Display 87–108 MHz Without Case Board 95.5 x 59 mm Speaker 3 W

The FM radio kit with display is a soldering kit from which you can assemble a receiver with a clear four-digit LED display. The radio receives stations in the range of 87–108 MHz and operates with the RDA5807 module, which ensures noise suppression, bass enhancement, high sensitivity, and resistance to interference. This version is supplied without a case, so the finished board remains open, making it easy to explain the functions of individual circuits. The kit is intended for hobbyists, students, and school clubs who want to build something more than just a blinking LED. Components are soldered manually, and the package does not include a soldering iron or solder.

The display replaces simple LED indication and facilitates orientation during tuning and working with stored stations. The radio can search for stations automatically, save them to a preset list, display signal strength, and remember settings after being turned off. There is also a power-saving mode and the option to adjust the search threshold to capture weaker stations. Volume is adjusted with buttons in 15 steps and sound comes from the 4 Ω 3 W speaker. You can connect headphones or an external speaker to the 3.5 mm jack.

We recommend starting by soldering resistors and small components, then installing sockets, connectors, buttons, and finally the display and module. Insert the integrated circuit into the socket only after completing the soldering to avoid overheating. Pay attention to the orientation of the display and the polarity of the capacitors. Use the finished open board on a dry, non-conductive surface and protect it from metallic objects that could cause a short circuit.

The version with a display is a great next step for anyone who has already completed their first simple soldering projects and wants to build a device with a real user interface. The finished radio offers convenient control, automatic tuning, and presets similar to those found in standard receivers. The open board without a case also allows for easy monitoring and potential adjustments of the connections. Powering via USB 5 V can be done with a standard phone charger or computer. The kit will delight young electronics enthusiasts, students in technical fields, and adult hobbyists.
