Can these be charged with the SparkFun USB LiPoly Charger Single Cell breakout?
about a month ago
Will this charge an 18650 cell? And is there any concerns over using protected/unprotected cells? The ability of the charger to stop charging the battery when it reaches the target voltage, is that a function of the charger or the battery?

I think the OLED shield is just the coolest. I don’t know if it’s just me, but I’m a sucker for anything with a display.

YOU WANT ME TO PUT THE SOLDERING IRON DOWN!!??
How hot do these get? I’m looking to go from 12V to 5V @ maybe 100-200mA. I don’t see anything in the data sheet. I don’t see how a heatsink could be attached. I was going to use a 7805 with a heatsink in my project, but it’s turning out to be just a little to big for the space I have to play with. If this needs a heatsink, or some extra room for airflow, then it might defeat the purpose of using instead of the 7805.
Look at the schematic. ON is connected to a MOSFET. Connecting anything higher than 5V will surely let the smoke out. This needs a HIGH or LOW signal, not VIN.

I hope people understand this and don’t start a flame war in the comments. I hope people understand that when your shipping cost is higher than the profit on the material being shipped, it’s only a matter of time before you have to close your doors.
