Description
We use a lot of the DFRobot DFPlayer Minis in our projects. To speed up prototyping, we breadboarded then made a custom carrier board that includes enough components to hook up the DFPlayer Mini to an Arduino or any other serial-capable controller (assuming a 5V supply).

To make it completely self-contained we grabbed some tiny 2W 8Ω speakers from Amazon and shoved them into the case shown here. We ended up hot-gluing them onto the bottom; very minor tweaking should make this a better press-fit solution, but we'd hot-glued the speaker wires to make them even more secure so it didn't fit quite right.
