Witztronics WTLCD050R

The WITZTRONICS WTLCD050YR LCD cape provides a 5.0” primary display with resistive touch for the Beagle Bone Black. It allows for a direct user interface and information display to the BBB.

The WTLCD050YR LCD cape was designed for the Beaglebone Black.

The WITZTRONICS WTLCD050/ LCD cape features a 5.0” diagonal, WVGA, 800 x 480 resolution display, resistive touch screen, 7 pushbuttons and a user programmed LED.

The Beaglebone Black attaches directly to the back of the WTLCD050YR or can be used at the top of a BBB stackup of other cape products that utilize the other signals.

The WTLCD050R utilizes drivers included in the Angstrom and Debian distributions for the BBB. Therefore allowing for an easy out-of-the-box experience.

The WITZTRONICS WTLCD050YR LCD cape features 7 push buttons next to the LCD display. Up, Down, Left, Right and Enter are arranged in an ergonomically useful joystick type pattern. Reset and Power are kept separate to help eliminate accidental use.

Four mounting holes are provided to secure the WTLCD050YR LCD cape into the users system.
