Rev.A (NOTES): It's a 5V charger powered by 2x AA cells! I use this to charge my USB devices or power low power prototypes. The Linear LT1302 Boost IC limits the current to 600 mA. So the charge rate will be moderate. You can think of this board as the SMD version of the popular Mintyboost, due t…

So the charge rate will be moderate. You can think of this board as the SMD version of the popular Mintyboost, due to the similarity of design. I’ve also added some testpoints to aid hacking/debugging. A thorough testing has yet to be completed. So be cautious as the battery heats up while charging. Use of fresh quality AA is the way to go. Pls feel free to email if you have issues or ideas to improve it. My next goal for this board is (a) to get rid of the SMD caps (for ease of soldering), and (b) increase the current limit. Thanks!
