The board design has been updated since this version:
- I missed off a pull up resistor on CH_PD (but can easily be tacked on the back of the board if you use this version)
- redesigned the layout so my fingers could get at the switches ;-)
- Added a switch to bypass the regulator so the circuit could be used either with 3.2v LifePO4, or 3.7v Li-ion batteries
