BeagleBone LCD Cape

The BeagleBone Battery Cape provides a portable power solution for BeagleBone boards and its capes. This cape provides 5V power supply to the BeagleBone using 4 Lithium AA battery cells. Power will be provided to BeagleBone’s VDD_5V power rail as soon as battery cells are installed. The BeagleBone Battery Cape is also equipped with a power switch, a power indicator LED, and an EEPROM for muxing configuration.

Software Support

Note: The low battery output LBO signal (mapped to GPIO1_16) and voltage level analog input AIN4 are not supported by the current software.

Getting Started

Required Setup:

  • A BeagleBone Battery Cape
  • A BeagleBone
  • 4 AA Lithium battery cells

Following the instructions below to start using your BeagleBone Battery Cape:

  1. Mount the Battery Cape on the BeagleBone.
  2. Install 4 AA Lithium battery cells to the battery holders. Each holder should only hold one cell.
  3. As soon as battery cells are installed, the BeagleBone will power on.
    • Note: Due to holder configuration, BeagleBone will power on as soon as two battery cells on one wing are installed. This is normal. You can keep installing battery cells on the other wing
  4. The Power LED on the Battery Cape and BeagleBone should be lit.

You can start using your BeagleBone.
