Kitronik FM Radio Kit V2.0

The Kitronik FM Radio Kit V2.0 is an electronic project kit designed for assembling a fully functional FM radio. It features industrial surface mount ICs (Si4820 and NCP2890) pre-mounted on the board, allowing users to easily solder remaining components to complete the kit.

The radio includes controls for tuning and volume adjustment, an audio amplifier, and a 66mm diameter speaker provided in the kit. The circuit operates on 2.5V to 5.5V power, compatible with a 5V wall supply or 3x AA batteries (not included).

Ideal for educational purposes and intermediate electronics enthusiasts, this kit promotes hands-on learning of radio technology and soldering skills.
