- Design it, remembering to fix bugs of rev1
- Decide on on/off solition, heavily leaning towards: LTC2954 with SI4465ADY
- Doublecheck that the 3.3V reg on the XMega board will not throw a hissy fit if we provide 3.3V from the partyboard (with and without 5V to xmega board provided)
- In any case MCP1826T looks like a good choice for regulator (very low drop even at high current) and decent price.
- Consider MCP73837 as alternative LiPo charger
