Awesome little amp!
Wonderful little power amp. Runs cool, sounds clean.
I feed mine from a laptop charger that puts out 19V 4A, and it works great!

Best of the bunch
There are several STM32F407V boards out there. This is the one you want.
Schematics are available on the STM32-Arduino site, and all three that I ordered worked out-of-the box for me.

Worked out-of-the-box
Worked out-of-the-box, allowed me to do double-sided printing on my HP2015 printer.
