FM Radio Kit for Soldering with OLED Display 87–108 MHz RDA5807 Chip 18650 Battery Power Transparent Acrylic Case Soldering Education
You already have the maximum available quantity in your cart.
This FM radio kit is designed for anyone who wants to learn to solder while building a fully functional receiver that they will actually use. The radio receives stations in the range of 87–108 MHz and is powered by the reliable RDA5807 chip. The current frequency, signal strength, volume, sleep mode, and battery status are displayed on a clear OLED display. The kit comes as individual components that you will assemble onto a printed circuit board and solder. It is therefore suitable for electronics education in schools, technical clubs, and for DIY enthusiasts who want to try building a radio from start to finish.
The finished radio is housed in a transparent acrylic case, allowing visibility of all electronics including the board, speaker, and battery. It is powered by a single 18650 cell, which can be charged directly in the radio via USB. The battery is not included. Control is managed by five buttons for volume, station tuning, and automatic scanning, along with a power switch and charging indicator.

You will need your own soldering iron, solder, and basic tools, which are not included in the kit. When assembling, carefully follow the markings on the board and pay attention to the correct polarity of the capacitors and battery. Remove the protective film from the acrylic parts only before assembling the case to avoid scratching the surface. Store the finished radio in a dry place and charge it with the power switch turned off, as recommended by the manufacturer. You can connect headphones to the jack whenever you want to listen quietly without disturbing others.
The kit offers a fun and practical way to learn to solder and understand how a radio receiver works. The result is not just a practice board, but a real radio with a speaker, display, and its own battery that you can use at home, in the workshop, or at the cottage. Thanks to the transparent case, the entire construction remains visible, and the finished product also serves well as a demonstration in teaching. The kit makes a great gift for budding electronics enthusiasts, students, and experienced DIYers. Just add a 18650 battery and your own radio can play.
