Plug-in connectivity options for integrated display modules
Under the name modules-on-the-go (MOTG), the series provides a simple plug-and-play interface to the 4D Systems gen4 range of DIABLO16 and PICASO intelligent display modules. As part of the range, 4D Systems has developed the Universal MOTG Interface (UMI), which is published as an open standard.
Initially the MOTG range comprises four modules, providing WiFi, Bluetooth (BLE), RS232 or RS485 connectivity. The modules plug into an interface board that also links to either a gen4 DIABLO16 or PICASO display. A fifth MOTG module adds MP3 playback functionality.
The MOTG-WiFi-ESP module provides WiFi connectivity through an Expressif ESP8266 WiFi SoC for use in IoT/Industrial IoT applications. Bluetooth 4.0 / 4.2 / low energy connectivity comes with the MOTG-Bluetooth module, which incorporates a Microchip BM70BLES1FC2 device. Serial communication is accommodated with either the MOTG-RS232 or MOTG-RS485 (differential) modules. In addition to the MOTG connectivity modules, the MOTG-MP3 provides MP3 playback capability using a 16-bit MCU audio decoder.
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.
By developing the UMI as an open standard, 4D Systems encourages developers to implement it in any design. 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.
