So perhaps all I'll need is a small battery (recharged when DC power is available) attached to the pads on the BBB, and some software. I am looking for an orderly shutdown when DC power is removed - the sole purpose of the battery is to provide power just until the BBB can be shutdown properly. No need to be monitoring for a wakeup event (just power back on when DC power is restored). Can you point me to any examples of how to monitor the DC status (through I2C as you say below or any other way) and initiate the shutdown? Thanks.
