FM Radio Kit HU-017B V5.0 with RDA5807 Chip 87–108 MHz Four-Digit LED Display Speaker Transparent Case For Soldering Education
You already have the maximum available quantity in your cart.
The FM radio kit HU-017B in version V5.0 is a soldering kit from which you can assemble a functional radio receiver with a tuning range of 87–108 MHz using your own hands. The signal is processed by a receiving module with the RDA5807 chip, the entire radio is controlled by the STC8G1K17 microcontroller, and the sound for the speaker is amplified by the TDA2822D circuit. The tuned frequency is displayed on a four-digit red LED display, and you control the volume and tuning with four buttons on the front of the board. This kit is designed for beginners who want to learn to solder through-hole components, and it is equally suitable for teaching electronics in schools or clubs. The finished radio can be placed in a transparent plastic case, so the entire circuit remains visible.
The purple printed circuit board has printed component markings, making it easy to identify where each component belongs and how it should be oriented. Both integrated circuits are inserted into sockets, so you do not need to solder them directly onto the board and can easily replace them if necessary. For listening, there is a built-in speaker, and if you want to listen quietly, you can connect headphones to the socket on the side of the board. For better reception of stations, a telescopic antenna is included in the package, which you can screw onto the board and extend above the case.

Before soldering, sort all components and proceed from the lowest parts, starting with resistors and ceramic capacitors, through sockets and buttons, to electrolytic capacitors, the display, and connectors. For electrolytic capacitors, LED diodes, and integrated circuits, ensure the correct polarity and orientation according to the markings on the board. Batteries are not included in the package.
The HU-017B V5.0 soldering kit combines practical soldering practice with understanding how a modern digitally tuned receiver works. The result is a finished FM radio that displays the tuned frequency on the display, plays through its own speaker, and can be powered via USB. Thanks to the transparent case, every soldered component is visible even after assembly, which is especially appreciated by teachers and club leaders. The kit is suitable as a gift for young DIY enthusiasts and as a training set for anyone looking to improve their electronics skills.
