Description
The Power Cape is an advanced power supply and control cape for the BeagleBone. It 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 power the BeagleBone from the single-cell Lithium battery, a DC power source, or a combination of the two (think solar). You can have the BeagleBone power up on DC power restore, configurable timeout, or an external signal. When the BeagleBone powers off, DC power is cut completely to prevent additional power draw for a lower power "off" state.
In addition to the power supervisor duties, 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.
Revision Changes
Revision A0
Initial release of BeagleBone Power Cape
Revision A1
- Molex connector removed from opto-isolator so that it's not the same as the DC input connector.
- UART1_TXD and UART1_RXD resistors are de-populated. These signals were tri-stated (available for other capes) on the A0.
- The cape now has access to the power button (PWR_BUT) and system reset (SYS_RESETn).
Revision A1a
Auxilliary connector footprints added to DC, battery, and power switch. Connectors are 2-pin MTA-100 style.
Getting Started
Standard setup:
- An AndiceLabs Power Cape
- A BeagleBone Black or BeagleBone White
- A 5V DC power supply (recommended 5V @ 2A)
- A single-cell (3.7V) LiPo battery
