    Has anyone had any luck figuring out what’s actually on the board? 7 transistors, a 5-pin IC, and what is probably a uC with an STVD logo on it that’s not really getting me anywhere… The inductor near the 5-pin device points to a boost converter, but what about charge control of the LiPo, which seems to be the burning question for everyone? Or is this a waste of time since figuring out the charge control algorithm would be extremely difficult? I’m curious how efficient this guy is at source/load balancing if there’s sun but not quite enough to power the 5v out.

No public wish lists :(
