Do you want to add a small, lightweight portable audio output to your project? With this mini stereo audio amplifier, add one (mono) or two (stereo) of our mini speakers, and a 3.5mm audio cable (plus a little soldering)...it's a snap! Sound quality is analogous to a standard smartphone using this amplifier and our recommended speaker. NOTES Changing any component parameters may damage IC Soldering is easy enough for an ameriDroid intern, so you can do it!
