The SparkFun Noisy Cricket is a compact stereo amplifier board based on the LM4853 Boomer IC. In its default stereo configuration, it delivers 300 mW per channel into 8 Ω speakers. Solder two jumper pads on the back to switch to mono mode for up to 1.5 W into a single 4 Ω speaker.

A dual-ganged potentiometer with built-in power switch controls both volume and on/off — just wire up power, audio input, and speakers to get going.
