FM Radio Kit with RDA5807 Chip and LED Display Soldering Set with Speaker USB-C and STC15 Microcontroller for Electronics Education
You already have the maximum available quantity in your cart.
The FM radio kit is a soldering set from which you will assemble a fully functional receiver with your own speaker and digital display step by step. The radio module with the RDA5807 chip takes care of station reception and tuning, the entire radio is controlled by the STC15 microcontroller, and the tuned frequency is displayed on a four-digit LED display. The finished receiver plays through the built-in speaker, and you can connect headphones or external speakers to the 3.5 mm jack. The kit is designed for anyone who wants to learn to solder, understand how a radio works, or simply enjoy working with electronics. It is suitable for school education, electronics clubs, home DIY enthusiasts, or as a unique gift.
The components are mounted on the main printed circuit board with labels, so you can easily see where each part belongs. Most parts are standard leaded components, the microcontroller and amplifier are inserted into sockets, and the radio module is already mounted on a small board. In one assembly, you will practice soldering resistors, capacitors, transistors, connectors, and the display. Finally, you will screw the main board to the front and back panels using spacers, resulting in a compact radio measuring 95 x 59 x 25 mm. The sound is amplified by the integrated circuit TDA2822M and directed to the 8 Ω 0.5 W speaker.

- Contents of the package – main printed circuit board, front and back panels, RDA5807 radio module, STC15W408AS microcontroller, TDA2822M amplifier with sockets, other small integrated circuits, four-digit LED display, 8 Ω 0.5 W speaker, telescopic antenna, resistors, ceramic and electrolytic capacitors, 4 transistors, trim pot, LED, 4 buttons with yellow caps, slide switch, 3.5 mm jack, USB-C connector, holder for 2 AA batteries, 8 spacers, screws, 2 adhesive pads, wire, and power USB cable (batteries not included)
For assembly, you will need a soldering iron, solder, and ideally, wire cutters to shorten the leads. We recommend starting with the smallest components, namely resistors and sockets, and gradually progressing to capacitors, transistors, buttons, displays, and connectors. Insert the integrated circuits into the sockets only after finishing the soldering and pay attention to the correct orientation according to the markings on the board. Keep the finished radio dry and do not leave it in direct sunlight.
This soldering kit combines fun and useful education in one package. The result is a real FM radio with a telescopic antenna, digital display, and its own speaker that you can use every day after assembly. Thanks to the power supply via USB-C or from AA batteries, you can easily connect it at home or on the go. The kit is suitable for beginners who have already mastered their first simple projects, as well as for more experienced DIY enthusiasts. It can be used in schools, at clubs, or during joint creation with parents and children.
