Power Failure Protection

CPU is with 1x GPIO for external power supply mode detecting, when external power input voltage is above 8V, IO will be high level, and PG green LED on case is lighting; otherwise IO will be low level and PG green LED will be light off.

When external power input cut off, system will be automatically switch to get power supply from supercapacitors and the PG red LED will be lighting, the supercapactiors could supply power at least 15 seconds and detect whole unit internal 5V main power voltage. When voltage falls more than 10%, the whole device will be cut off to avoid system failure because of overlow voltage
