FM Radio Kit for Soldering 87.5-108 MHz with LED Display Amplifier 3 to 5 W USB-C 5 V Power Supply and 3x AA Acrylic Box for Education
You already have the maximum available quantity in your cart.
The FM radio kit is a soldering set from which you can assemble a functional radio receiver in a transparent box. The heart of the radio is the receiving RDA5807M chip, which covers the entire FM band ranging from 87.5 to 108 MHz. Control is managed by the STC8G1K08 microcontroller, and the tuned frequency or current volume level is displayed on a four-digit LED display. The kit includes a printed circuit board with component labels, a speaker, a battery holder, a telescopic antenna, and all parts of the acrylic box. It is suitable for DIY enthusiasts, students, and electronics clubs, where interested individuals can practice soldering on a real product.
The sound is managed by a digital AXS2031 amplifier with an output power of 3 to 5 W, which operates within a voltage range of 2.5 to 5.5 V and, according to the manufacturer, plays without distortion even at lower voltages. The power supply for the control section is provided by a 3.3 V buck-boost module, which maintains a stable voltage for the microcontroller and display even when the input voltage drops to 2.5 V. You can power the radio either through the USB-C connector from a 5 V adapter or from a power bank, or from three AA batteries. Both power supply methods cannot be used simultaneously. For better reception, there is an omnidirectional telescopic antenna measuring 30 cm, which can be rotated in any direction.

The controls are simple. A short press of the tuning buttons changes the frequency by 0.1 MHz, while a long press initiates automatic station scanning. The other two buttons adjust the volume, and a blue indicator light shows that the radio is powered on. When assembling, first compare the components with the list and solder progressively from the lowest parts to the highest. The box can be assembled only after successfully powering up the board. Protect the finished radio from moisture and dust, and remove the batteries during prolonged periods of non-use.
This soldering kit combines fun with a useful outcome, as it leaves you with a fully functional radio for your desk once completed. The board with labels and the clear arrangement of components make it easier for even less experienced DIY enthusiasts. With two power supply options via USB-C or AA batteries, you can use the radio both at home and on the go. The entire electronics remain visible in the transparent acrylic box, making the product a great educational tool. The kit is suitable for schools, electronics clubs, and as a gift for technically inclined enthusiasts.
