Overview
FM Transmitter Kit 88-108 MHz with Microphone and 3.5 mm Audio Input Soldering Kit RF-02FM with Board 53 x 40 mm For Teaching Electronics

The RF-02FM FM transmitter kit is a soldering kit from which you will assemble a small radio transmitter operating in the 88-108 MHz band. The signal from the transmitter can be picked up by a standard FM radio, allowing you to experience how sound transmission works through the air. Sound can be captured directly via the built-in electret microphone or fed from a phone or player through the 3.5 mm audio input. Depending on the environment and antenna, the transmitter achieves a range of 5 to 50 m. The kit is suitable for teaching electronics, clubs, DIY projects, and as an interesting project for beginner radio amateurs.

The circuit is built using standard leaded components that are mounted onto a printed circuit board measuring 53 x 40 mm. The board clearly marks the positions of all parts, making assembly manageable even for beginners. The transmitter is powered by a direct current voltage of 3 to 6 V, which connects to a screw terminal block. The board also features a red LED, and the antenna is made from the included wire connected to the soldering point ANT.

  • Model – RF-02FM
  • Transmission Frequency Range – 88-108 MHz
  • Range – 5 to 50 m
  • Power Supply – DC 3 to 6 V via screw terminal block
  • Operating Current – 5 to 15 mA
  • Sound Source – electret microphone or 3.5 mm audio input
  • Audio Input Level – max. -15 dB
  • Printed Circuit Board – 53 x 40 mm
  • Mounting Type – leaded components for manual soldering
  • Contents of Package – printed circuit board 53 x 40 mm, resistors, ceramic capacitors, electrolytic capacitor, coils, transistors 9014 and 9018, electret microphone, 3.5 mm audio connector, screw power terminal block, LED, antenna wire, and parts list (batteries not included)

Before starting assembly, prepare a soldering iron, solder, and wire cutters for trimming leads. Begin with the lowest components, namely the resistors and ceramic capacitors, followed by transistors and coils, and finally the microphone, audio connector, power terminal block, and antenna. Mount the coils closely to the board and ensure the correct polarity for the electrolytic capacitor. Do not leave the soldering iron tip on the component for too long to avoid damage. After connecting the power, tune the radio to the transmitter frequency and test the reception.

The FM transmitter soldering kit combines soldering practice with a practical demonstration of radio transmission. The result is a functional transmitter with an electret microphone that you can use for experiments at school or to transmit sound from a player connected via the 3.5 mm audio input to a radio in another room. Thanks to the simple circuit and clear markings on the board, the kit is suitable for both beginners and advanced hobbyists. It can be used in education, in electronics competitions, for personal projects, or as a gift for anyone interested in electronics. For a complete experiment, you can complement it with an FM receiver kit.
