DESCRIPTION 

This Whisker uses the NCP2820 to amplify audio. With more than 90% efficiency, this low-power amplifier will save the lifetime of your battery.

The Whisker Adapter TinyShield (ASD2022) incorporates level shifting and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.
