MOTG-96 is a tiny pluggable module ideally suited as a diagnostic display for embedded systems. It incorporates a 0.96" 96×64 resolution full-color Passive Matrix OLED and has a wide range of uses such as educational, experimental, or during any development phase where a quick display solution is required. It comes in a microSD memory card format which is designed to interface to any embedded platform that has an on-board microSD card slot.

Powerful graphics, text, image, animation and other features are built into the MOTG-96. The display module utilizes standard SPI signals and acts as a slave device to the host microcontroller. It offers a simple yet effective command set to any host platform that can communicate via a SPI port. All screen-related functions are sent using a simple protocol.

The MOTG-96 device simply plugs into a standard µSD socket for quick assembly and maintenance. Don't need the device permanently, or want to make it optional? Simple; just unplug. Need some way of debugging your latest brainchild without top-end equipment? Just plug a MOTG-96 into its µSD socket and use it as an outboard diagnostic display.

microSD OLED Display Module Resources

• MOTG-96 module datasheet


• PmmC File: The GOLDELOX chip used in the MOTG device is a custom controller, and all functionality including the high-level commands are built into the chip. The PmmC file contains the low-level micro-code information (analogous to soft silicon) which defines the characteristics and functionality of the MOTG device. Programming the device with a PmmC file provides a flexible method of customizing as well as upgrading the MOTG with future enhancements. The MOTG module comes with this default PmmC already loaded.


• PmmC Loader Software Tool: This is a Windows-based software tool to program a PmmC file into the MOTG module.


• FAT Controller Software Tool: This is a free software tool to test the functionality of the MOTG device using your PC prior to writing any piece of embedded code for your platform. The FAT-Controller simulates the embedded host controller and provides an easy means of exercising the available commands.


• Embedded C Library Driver Source: Use this C source code to embed the functionality of the MOTG Display module into your host platform.
