i am looking for something like this
for regular arduino.
the project i am working on is http://www.instructables.com/id/Make-your-own-smart-watch/
i want to replace the lipo cell with a rechargeable setup. but to put a charging breakout would just add to the bulk and i am trying to keep it as thin as possible. also would like to be able to charge in-line without having to remove the battery or connection from the battery from the controller to charge.
any one know of something like the link above that would work?
