Initially I was thinking of a simple ON/OFF switch that disconnects the battery, but I realized I need it to be able to charge a Li-Po battery while the device is powered down. Now since I'm charging a Li-Po I need to output 4.2V to the charger (at say 50-100+ mA or something comparable to the current from the battery terminal). Sadly as this is a new board I don't have much in the way of a spec sheet to guide me on the capabilities of each port.
- Will I fry the board if I try to run power through analog out ports?
- Is there charging behavior that is built into Li-Po charging that I need to emulate on the analog out that I use?
