Descriptions

BeagleBone LCD Cape

The BeagleBone LCD7 Cape provides an LCD solution with touchscreen capability for BeagleBone boards. The 7" TFT LCD screen, attached to the topside of the board, can display up to a resolution of 800x480 and is a 4-wire resistive touchscreen. The board is equipped with seven buttons located at finger-friendly positions. These buttons include power, reset, and five user buttons, which are mapped to different GPIO signals. The backside of the cape is where the BeagleBone and additional cape can be mounted.


Note: Bracket stands are not included

Revision Changes

Revision A3

In revision A3 the Enter button has been moved from GPIO3_19 to GPIO0_3 and LCD_DVDD_EN has moved from GPIO1_31 to GPIO0_2. These changes in GPIOs are to support awake interrupt in sleeping mode.


The PCB revision is also changed from BB-Bone-LCD7-PCB-03 to BB-Bone-LCD7-PCB-04.


Revision A2

The only design change in A2 is that the LCD_AVDD_EN signal is moved from pin 42 of connector J2 to pin 20 of connector J1. In revision A1, LCD_AVDD_EN signal is mapped to GPIO0_7 which is also a DMA interrupt. By moving LCD_AVDD_EN signal, this DMA interrupt is now available when BeagleBone is used with LCD7 Cape. Both revisions should not have any functional difference.


The PCB revision is also changed from BB-Bone-LCD7-PCB-02 to BB-Bone-LCD7-PCB-03.

Getting Started

Required Setup:

  • A BeagleBone LCD7 Cape
  • A BeagleBone (with supported software)
  • A 5V DC power supply (we recommend 5V - 2A)
  • A Stylus (optional)


Following the instructions below to start using your BeagleBone LCD7 Cape:

Mounted BeagleBone
  1. Mount the BeagleBone to the BeagleBone Connectors on the LCD7 Cape.
    • Note: The BeagleBone Connectors are the set of male connectors on the backside of the LCD7 Cape.
  2. Make sure the SD card using with BeagleBone has Angstrom image 6-18-12 or later.
  3. Plug in a 5V DC power supply to the DC connector on the LCD7 Cape.
    • Note: We recommend using a 5V - 2A supply. However, more current supply may be required if more capes or peripheral devices are connected.
  4. Following screens will be displayed on the LCD screen:
    • BeagleBone logo
    • Angstrom log-in prompt
    • Auto Calibration utility
  5. Follow the instructions given by the Auto Calibration utility to calibrate the LCD7 touchscreen.
    • Note: The Auto Calibration utility is automatically displayed when the card is used for the first time. This utility can be run again under menu System > Administration > Calibrate Touchsreen
  6. After calibrated, the Angstrom desktop will be displayed on the LCD screen.


You can start using the board.
