The LiPoly backpack sits neatly on top of the Pro Trinket with the three pins (BAT, G, 5v/BUS) aligning.  

To enable the on/off switch capability, cut the trace between the two switch pads with a utility knife.

Power the Neopixel Jewel by soldering to the two power pads on the back of the Pro Trinket.
