FM Radio Kit for Soldering with LCD Display 1602 and RDA5807 Chip 87–108 MHz 5 W Amplifier Acrylic Box for Electronics Education
You already have the maximum available quantity in your cart.
This kit allows you to build your own digital FM radio from the ground up. The heart of the receiver is the proven radio chip RDA5807, which captures stations in the 87 to 108 MHz band with a tuning step of 0.1 MHz. The tuned frequency and current volume are displayed on a clear blue backlit LCD 1602 display. The kit is designed for anyone who wants to learn to solder and understand how the electronic circuit of a radio receiver works. The finished radio can serve as a functional addition to your desk, workshop, or room.
The sound from the radio is provided by a built-in amplifier with a power of 5 W and an output impedance of 4 Ω, which drives the included speaker. Above the display is a series of LEDs that function as a colour spectral indicator, flashing in time with the music. The indicator can be turned off at any time with a separate button. The controls are simple: the left button turns the radio on and off, the S+ and S- buttons adjust the volume, and the P+ and P- buttons change the received frequency and search for stations. The entire circuit is controlled by an STC microcontroller, which is inserted into a socket, preventing damage from heat during soldering.

- Package contents – printed circuit board, LCD display 1602, RDA5807 module, STC microcontroller with socket, crystal, speaker, telescopic antenna, power cable with USB connector, power connector, LEDs, integrated circuits, resistors, capacitors, buttons, pin headers, parts of the transparent acrylic box, and mounting screws with nuts and spacers
Components are placed on the board in described positions, making it easy to identify where each part belongs. You will need a soldering iron, solder, and basic tools, which are not included in the package. After soldering and powering up the board, the entire radio is placed into the transparent acrylic box, through which the internal circuit and flashing LEDs are visible. The radio is powered by the included cable from a USB charger, computer, or power bank with a voltage of 5 V. For the best reception, extend the telescopic antenna and place the radio as close to a window as possible. The board and box only need occasional cleaning with a dry soft cloth.
The FM radio kit with LCD display 1602 is an excellent practical project for both beginner and advanced hobbyists, students, and electronics clubs. While assembling, you will practise soldering traditional leaded components and become familiar with the microcontroller, radio chip, and low-frequency amplifier. The result is a fully functional receiver in the 87–108 MHz band that actually plays. The transparent box measuring 90 x 70 x 55 mm protects the electronics while showcasing your work. The kit makes a great gift for anyone interested in electronics and creating with their own hands.
