You already have the maximum available quantity in your cart.
The FM radio kit with a transparent acrylic case is the ideal choice for anyone who wants to try soldering and end up with a finished desktop radio that has an appealing look. The receiver uses the RDA5807M module with high sensitivity, which tunes into stations in the 87.5–108 MHz band. Control is managed by the STC15W408AS microcontroller, and sound is handled by the AXS2031 digital amplifier. The output power of 5 W + 5 W is directed to two speakers located on either side of the board. Components and case parts are supplied loose, allowing you to assemble the radio with your own hands.
The transparent acrylic cover consists of a front and back panel, side panels, and feet, held together by brass spacers, nuts, and screws. The electronics remain clearly visible after assembly, making it easy to see how the radio is wired. The four-digit LED display with blue digits shows the frequency or volume, and four buttons are used for tuning and changing the volume. Long pressing starts automatic station scanning, while short pressing changes the frequency by 0.1 MHz. Power can be supplied via USB-C or from a 18650 lithium cell, which charges directly when connected to USB-C.

When building, it is advisable to first check all components against the list and solder progressively from the lowest to the highest. First, secure the antenna with a screw and then solder it. After populating the board, the brass spacers are screwed in, the front cover is attached, followed by the side panels, and finally the back panel. The cover protects the soldered joints and also makes the radio a finished piece that can stand on a table or shelf.
The kit is suitable for school clubs, electronics education, and as a gift for technically inclined DIY enthusiasts. The result is a stereo radio with two speakers, a clear display, and a transparent acrylic cover. Thanks to the option of powering from a 18650 cell, it can also be used without a cable. Headphones or an additional amplifier can be connected to the 3.5 mm output. The version with the cover is therefore suitable for anyone who wants a finished desktop radio right after soldering.
