FM Radio Kit HU-017B with Transparent Case RDA5807 87-108 MHz Four-Digit LED Display Soldering Kit for Electronics Education
You already have the maximum available quantity in your cart.
The FM Radio Kit HU-017B is a soldering kit from which you can assemble a fully functional radio receiver with a digital display. The heart of the receiver is the RDA5807 module with noise suppression, bass enhancement, and high sensitivity. The radio receives the 87-108 MHz band and displays the tuned station and signal strength on a four-digit LED display. This kit is designed for electronics education in schools, clubs, and at home, and is suitable for beginners who want to try soldering on a real project. The finished radio fits into a transparent plastic case, allowing visibility of the entire board.
When powered on, the radio automatically searches for nearby stations and saves them to memory, which is retained even when turned off. Up to 30 stations can be saved. Control is managed by four buttons: a short press switches the volume or the previous and next station, while a long press smoothly adjusts the volume or starts the search. The volume has 15 levels, and the search sensitivity can be adjusted to capture even weaker signals. Sound comes from the built-in speaker, and headphones or an external speaker can be connected via the 3.5 mm jack. The power-saving mode reduces consumption when running on batteries.

Components are mounted on the board with labels and soldered using a standard soldering iron, which you need to provide yourself. Integrated circuits are inserted into sockets, so they do not need to be soldered directly during assembly. After completion, the board is placed in the case and screwed together with the provided screws. The transparent plastic case can be easily wiped with a dry cloth; protect the electronics from moisture.
The HU-017B kit combines fun soldering with a result that can be used every day. After assembly, you will have a small tabletop radio with station memory, display, and speaker. Thanks to the transparent case, you can see how the individual components on the board work together, which is especially appreciated by children and students. The kit can be used as a gift for a young DIY enthusiast, an educational tool, or a standalone weekend project. Powering via USB cable or batteries allows you to listen to the radio both at home and on the go.
