Add connectivity to gen4 display modules

The modules-on-the-go (MOTG) series from 4D Systems provide a plug-and-play interface to the gen4 range of DIABLO16 and PICASO intelligent display modules. This open interface standard responds to the demand for additional display module interface and communication capabilities. The MOTG approach provides an extremely quick and convenient method of adding a host of low-profile connectivity options to the gen4 display modules.

The modules offer a simple plug and play interface to Universal MOTG BUS (UMI) allowing rapid assembly and maintenance. This removes the hassle of having to solder and end up with a wiring nest. It also allows the designer to easily remove the existing module or add another module instead, which could be very useful during the phase of prototyping.

 

Three breakout boards are available  to add these MOTG interface modules to a gen4 display. Connection to the gen4 DIABLO16 display module is via the MOTG-AC1 – a one-slot interface board, or the two-slot MOTG-AC2. The PICASO display module uses the MOTG-AC3 one-slot interface board.

 

To encourage developers to implement it in any design the UMI is developed as an open standard. Making this approach accessible to any embedded design is the MOTG-BREADTOOTH prototyping board, which allows the use of any MOTG module with virtually any host.
