stalker usb charger

G’day,

A usb charger would be pretty convenient for my project i have going,
i thought the solar charger connector would have a nice charging cct on it to apply the usb power to…and now my board doesnt work…
im keen to try it again as i think it should have worked but not to keen on killing another board…
should this have worked? or would you suggest another way of tackling this modification??

Cheers.
Glenn.
