LCD Displays for BeagleBoards


The gen4 CAPE series of TFT LCD display capes are designed specifically for use with the BeagleBone Black Single board computer. The gen4 CAPE series suits a wide range of applications that require a high-quality, easy-to-use and compact graphical display (monitor) to be incorporated into a BeagleBone Black-based design. The BeagleBone Black Wireless and BeagleBone Green boards are also supported.


The series comprises 4.3, 5.0, and 7.0-in. models, each equipped with a 30-pin robust FPC cable that plugs into the supplied gen4 CAPE adapter board. Power, control, and data signals come through the FPC so no additional connectors are required to operate the display.  Use of an adapter board permits ease of using different display sizes to suit the application. In addition, each gen4 CAPE has the choice of either resistive or capacitive touch options.


The resistive touch function uses an on-board Microchip AR1021 resistive touch controller that communicates directly with the BeagleBone Black over I2C in place of traditional LCD capes which utilize the analog inputs that are rather susceptible to external EMI. The capacitive touch models incorporate a cover lens bezel that enables the construction of a robust yet slim design with ease, utilizing Focaltec CTP controller that communicates over I2C.


The gen4 CAPE series comprises the following models:

-gen4-4DCAPE-43T 4.3-inch display with resistive touch

-gen4-4DCAPE-43CT-CLB 4.3-inch display with capacitive touch and cover glass

-gen4-4DCAPE-50T 5.0-inch display with resistive touch

-gen4-4DCAPE-50CT-CLB 5.0-inch display with capacitive touch and cover glass

-gen4-4DCAPE-70T 7.0-inch display with resistive touch

-gen4-4DCAPE-70CT-CLB 7.0-inch display with capacitive touch and cover glass


US$59 for single unit quantities of the 4.3-inch resistive touch models.
