FM Radio Kit TJ-56-750 with OLED Display and Charging 87–108 MHz Speaker 3 W Acrylic Box 117 x 72 x 27 mm Soldering Training
You already have the maximum available quantity in your cart.
The FM Radio Kit TJ-56-750 is an electronic kit for soldering, from which you will assemble a fully functional portable radio receiver. The heart of the circuit is a radio module with the RDA5807 chip, which offers noise suppression, bass enhancement, high sensitivity, and good resistance to interference. The radio receives stations in the 87–108 MHz band and can automatically search for and save them. The kit is suitable for beginners learning to solder, as well as for school clubs and electronics education. Once completed, it will result in a radio in a transparent acrylic box, allowing you to see the entire circuit.
Clear information is displayed on a small OLED screen, where you will see the battery status, signal strength, volume level, sleep mode, and current frequency. Power is supplied by a single 18650 lithium battery with a voltage of 3.7 V, and the board includes a charging circuit, so you can charge the battery directly in the radio via the charging connector. Sound is played through a 3 W speaker with a metal grille, and the volume can be adjusted in 15 levels, including mute. For private listening, there is a 3.5 mm audio output for headphones or an external speaker. The sleep mode helps save battery energy.

Controls are simple. A short press of the buttons changes the volume or switches to the next or previous station, while a long press smoothly adjusts the volume, starts searching for stations, or rescans the entire band. Before soldering, review the circuit according to the diagram and gradually assemble the components. Insert the 18650 battery into the holder with the correct polarity and clean the box with a dry cloth after completion.
This kit combines fun with practical learning, resulting in a radio that you will actually use. Thanks to the RDA5807 chip and the 3 W speaker, it offers clear reception and pleasant sound. The finished radio in a transparent acrylic box measuring 117 x 72 x 27 mm is suitable for a work desk, workshop, or travel. The kit makes a great gift for young technicians, students, and anyone who wants to try soldering electronics on an interesting project.
