POWER BOOST BASIC not working

[siteswapjuggler]

Hi,

I just ordered two of th power boost basic. It's a great breakboard but I got a problem with one of them. For now I soldered the USB connector on both and tested them. The first one works without any problems. But the second one doesn't seem to work at all.

Symptoms are : the PWR (green) LED lit for like 1ms and then directly shut down, no voltage at all when I connect my Voltmeter to GND and 5V pins or to the USB connector +5 and GND pin, good voltage from Bat et GND pins.

Do you have any clue to make it work ?

Thanks
Sylvain

Could we see the soldering on the bad one and the connections you have when testing? Thanks.

Yes sure I'll try to make a picture asap. I've check the soldering twice but could be wrong. And the connection is very simple I just have a lipo battery connected to it via the JST connector.
