Page 3: Overview
The Brightsign Compact is a device that can be used to drive a variety of HDTV and computer monitors for digital sign and kiosk applications. As well as driving the Video Display, the Compact has many different control interfaces built in to allow the sign to be controlled. - Page 4 BrightSign Compact Compact Block Diagram This information applies to a product under development.

500mA to an external device. The 3.3V output is polyfuse protected and can source up to 500mA. If a Brightsign is driving the inputs on another Brightsign, then you can at most drive 3 inputs from 1 output. Calculations follow showing why this is: The GPIO outputs have 100 Ohm series resistors, the inputs have 1K pullup resistors to 3.3V, and the... - Page 7 Ground Button 0 I/O DA15 female as viewed from the back of Brightsign Compact: Roku makes a button/LED/IR board that can be used to demonstrate how the GPIO and IR works. Here is the schematic to that board as an example of how to connect things to the GPIO connector: This information applies to a product under development.
- Page 8 BrightSign Compact In this example schematic, we are using a Vishay TSOP39338 IR receiver, which can operate properly on 3.3V. The TSOP39138 will also work. We are using a Honeywell SEP8506-003 IR Diode as the IR blaster output. This information applies to a product under development.

1080i video: Y from Green jack, Pr from Red jack, and Pb from Blue jack. 1/8” Audio connectors The Brightsign Compact has one 1/8” female audio connectors. The connector has a stereo audio signal. The full scale voltage output of the audio is 2V RMS, with no load. The minimum load resistance that should be connected to the audio output is 5K Ohms. -
