This is the FM Radio kit with a audio amplifier built-in from Kitronik.
The FM radio kit uses industrial surface mount ICs (the Si4820 and the NCP2890). The FM radio kit is supplied with the ICs mounted on the board. You just have to solder the remaining resistors, capacitors and other components to finish the kit. The radio has controls for tuning and to adjust the volume. The circuit includes an audio amplifier and output is via a 66mm diameter speaker that is supplied with the kit.
The board can be powered from a 2.5V to 5.5V supply and works nicely off a 5V wall supply or 3x AA batteries (not supplied). The Si4820 IC is one of the latest generation of radio receiver ICs that offer fantastic reception quality and ease of tuning, and the NCP2890 IC can output 1W of power.
