In this video, I solder up some leads to this TPA3110 Bluetooth amplifier board and give it a listen. The Price, $3 to $6 ea. at the time of this video makes this a compelling choice for any small Bluetooth project you may have in mind.
This same basic board is sold on several websites in varying forms; mine was purchased from Banggood.
