We've also broken out the power-save and enable pins, so that you can have full control of the switching regulator. The under-voltage lockout enable is also tied to a solder jumper so that you can disable it if you like.
The micro-USB charger uses the MCP73831 and allows you to charge 3.7V LiPo cells at a rate of 500mA.
The boost converter is based on the TPS61200 from TI and has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V (which can be disabled via solder jumper on the back of the PCB).
Note: This board does not have reverse polarity protection, so please be sure to recognize the polarity of your connections!
