FM Radio Kit for Soldering with RDA5807 Chip and TDA2822 Amplifier Speaker Telescopic Antenna 18650 Battery Electronics Education
You already have the maximum available quantity in your cart.
This FM radio kit is designed for anyone who wants to build a functional receiver with their own hands while learning to solder. The kit includes a printed circuit board with printed component markings, all necessary components and parts to assemble a finished radio with stands. The reception of radio broadcasts is handled by the receiver chip RDA5807 and the sound is sent to the speaker by the low-frequency amplifier TDA2822. Stations are searched using buttons and the volume is adjusted with two additional buttons on the top edge of the board. The result is a desktop radio with visible electronics that you can proudly display or use for listening.
The kit is suitable for teaching electronics in schools, clubs, or at home. While assembling, you will practice soldering classic leaded components such as resistors, ceramic and electrolytic capacitors, coils, diodes, and LEDs, as well as mounting a socket for the integrated circuit. The board is populated on one side, and the green stands from the printed circuit board hold it in a vertical position upon completion. Power is provided by a rechargeable 18650 cell housed in a holder on the front of the board, and there is also a DC power connector and USB cable available. Reception is improved by a telescopic antenna that you attach with a screw in the top left corner. The labels on the board are in Chinese, and their meaning is clear from the placement of the controls.
- Type – FM radio kit for soldering
- Receiving Circuit – RDA5807 chip with a 32 768 Hz crystal
- Amplifier – TDA2822 integrated circuit in an 8-pin socket
- Control – 4 buttons for station searching and volume, and a sliding switch
- Power Supply – rechargeable 18650 cell in a holder and DC power connector
- Indication – 2 red LEDs
- Design – green printed circuit board with 2 stands
- Contents – printed circuit board, 2 stands, speaker, telescopic antenna, RDA5807 chip, TDA2822 amplifier with socket, crystal, resistors, capacitors, coils, diodes, 2 LEDs, 4 buttons, sliding switch, DC power connector, 18650 battery holder, 1 rechargeable 18650 battery, speaker wires, screws and nuts, USB cable, and assembly diagram
Before starting work, prepare a micro soldering iron, solder, and wire cutters. Populate the components according to the assembly diagram and the printing on the board, paying attention to the correct polarity for electrolytic capacitors, diodes, and LEDs. The speaker is screwed to the board with four screws and hex nuts, and the battery holder is secured with two countersunk screws. After completion, check the connections, insert the cell into the holder, and turn on the radio with the switch. Protect the finished board from moisture and metallic objects that could cause a short circuit.
The FM radio kit combines fun with practical learning and demonstrates how a modern radio receiver works. Thanks to the clear printing on the board and the assembly diagram, it can be managed by beginners as well as moderately advanced DIY enthusiasts. The receiver with the RDA5807 chip and its own speaker serves as a small desktop radio once assembled. The kit also includes a rechargeable 18650 battery, so after soldering, you just need to turn on the radio. It is a suitable gift for young technicians and a useful tool for technical education teachers.
