Overview
FM Radio Kit for Soldering RDA5807 65–108 MHz Without Display Speaker and 18650 Battery Holder Transparent Case For Learning Soldering

This FM radio kit for soldering is designed for anyone who wants to learn to solder and understand how a simple radio receiver works. The heart of the circuit is the receiver chip RDA5807, which captures broadcasts in the range of 65–108 MHz. The sound is amplified by the TDA2822 circuit and played through the built-in speaker directly on the board. The kit does not include a display, so the stations are tuned using search buttons, and the volume is adjusted with a pair of buttons. The finished radio, thanks to the transparent acrylic case, serves as a visual teaching aid, showcasing every component.

The printed circuit board measures 126 x 73 mm, and the positions of the components are labelled, making it easier to orientate during assembly. The board is equipped with a holder for a lithium 18650 cell, a power switch, and a charging connector DC 5 V, into which the included cable with a USB connector is connected. The telescopic antenna has a length of 85 mm in its basic position and can be extended up to 250 mm, which helps improve the reception of weaker stations.

  • Type – FM radio kit for soldering without display
  • Receiver chip – RDA5807
  • Amplifier – TDA2822
  • Frequency range – 65–108 MHz
  • Power supply – DC 5 V and lithium 18650 cell
  • Board size – 126 x 73 mm
  • Antenna – telescopic 85 mm with extension up to 250 mm
  • Controls – volume and station search buttons and a sliding switch
  • Case – transparent acrylic panels with spacers and screws
  • Battery – 18650 cell not included
  • Package contents – printed circuit board, receiver chip and amplifier, resistors, capacitors and other electronic components, speaker, 18650 cell holder with cable, telescopic antenna, 4 buttons, sliding switch, LEDs, acrylic case parts, spacers with screws, and USB power cable with DC connector

Before soldering, it is advisable to review the circuit diagram and sort the components by value. First, low components such as resistors are placed, followed by capacitors, buttons, the cell holder, and finally the speaker and antenna. A standard micro soldering iron, solder with flux, and side cutters for trimming leads will suffice for the job. Once completed, simply insert a charged 18650 cell, turn on the radio, and use the button to search for the first station. Finally, the board is placed between the acrylic panels, and the whole assembly is secured with screws through the spacers.

This kit is suitable for electronics clubs, school teaching, and as a home project for novice DIY enthusiasts who want to try building a real device. The result is a functional portable radio with its own speaker, which can be charged via DC 5 V and used without being connected to the mains. The combination of the RDA5807 chip, TDA2822 amplifier, and telescopic antenna ensures a simple circuit suitable for initial soldering attempts. The transparent case protects the board from damage while also displaying the entire circuit. Thus, the kit combines practical soldering practice with an understanding of the principle of radio signal reception.
