8x8 RGB LED Matrix Display Module [END OF LIFE]


Contents

Overview

NOTE: The main component for making this product was obsoleted by the manufacturer so we won't be able to manufacture it anymore. We will continue selling it while supplies last only.

Add a full-color 8 x 8 LED display to your next project! The RGB LED Matrix Display Module, based on Parallax’s multicore Propeller microcontroller, comes pre-loaded with factory firmware that supports a detailed command set. The module may be controlled with most microcontrollers, such as the BASIC Stamp, Propeller, Arduino, AVR, PIC, etc.

The RGB LED Matrix Display Module is fully customizable: you can re-write your own firmware, define your own protocol, or modify the Spin and C firmware available for download on our website. Or, you can use the factory firmware and your own custom computer software to configure the modules via the 4-pin header for Parallax’s Prop Plug.

Warning: Voltage- and Static-sensitive Device

  • RGB LED Module is a delicate, static-sensitive device requiring proper voltage
  • Observe proper anti-static techniques when handling them.
  • Disconnect all power before connecting or disconnecting the module to a circuit
  • Do not reverse polarity of the power connections, it could destroy the device.

Pin Definitions

Read pin labels on the board carefully when making connections. When read from the edge of the board, the top and bottom headers have the opposite pin sequence. So do the two side headers. This allows modules to be connected together. Only connect power to one VCC pin at a time. Only one GND connection is needed.

Pin Name Type Function
1 SIO Input Serial data input
2 VCC Power Supply voltage
3 GND Ground Ground (0 V)

Microcontroller Connection

You may connect the RGB LED Matrix module to a microcontroller through any of the module's SIO pins. Do not connect to more than one SIO pin at once. Note: the male 3-pin headers may be covered with removable protective caps. Capture 2.JPG
