does anyone have any experience with the ebay version of this amplifier board vs the kit being sold by the 2nd place winner of the nxp contest.
my pair of mrf300's arrived . thanks
 

and the rest of the candy store

Then our old friends Victor and Yana

But wait,

I'd be looking at cleaning up and regulating a 48-54V battery charger.
Unless you already have 48v+ at over 25A

A heatsink and a box to put it in wouldn't hurt either :)

Now if you are capable and or proficient

I think I still have the vector graphics and possibly the gcode as well as an outdated BOM.
Somewhere here is a better explanation but I'm out of time.
