Chapter 1 Product Overview

1.1 Introduction

BeagleBone-HDMI Cape (hereafter refers to BeagleBone-HDMI) is an extension board

development board that was built on TI’s Sitara AM335x microprocessors.

BeagleBone-HDMI is capable of providing HDMI output including both audio and video

signals with a video resolution of up to 720p. Additionally, it has a 50-pin LCD interface

for the connection of a 4.3- or 7-inch LCD display. The LCD and the HDMI interfaces are

working under multiplexing mode, which means only one of the interfaces could function

at a time.
