VPack 5v DC to DC Step up problem

Hello,

I can’t seem to get the Vpack PCB to work. I had one that wouldn’t work which I returned to Sparkfun and they sent me another one. I can’t get this one to work either.

I am soldering a jumper across J1. I am attaching a 3v battery:

plus to pad labeled “in” and minus to the gnd pad. I put a volt meter on the pad labeled “out” and gnd expecting 5v, but only get about 1.1v

This is such a simple product, I can’t understand what I am doing wrong.

Any idea’s would be appreciated.

Thanks,

Jack

I think they may gotten a bad set of boards. Another poster has reported that their board doesn’t work either:
