The BeagleBone Power Cape is a power supply and control cape for the BeagleBone that combines a dynamic power path manager and lithium battery charger with a buck/boost regulator and power supervisor to enable a variety of operating scenarios. For example, you can use the BeagleBone from the single-cell Lithium battery, a DC power source, or a combination of the two. You can have the BeagleBone power up on DC power restore, configurable timeout, or an external signal. In addition, the AVR provides a real-time clock function as well as configurable watchdogs for power-up and power-down of the system. System software can track the battery voltage and current via the INA219 power monitor on the battery interface.
