Development Kit


ema:Play provides a “sandbox” environment with hardware and software interfaces for customers to test and develop their ideas.

Product Details

Custom Hardware

OptConnect ema™ is a pre-certified LTE Category 4 Cellular modem with a 20-pin interface. In order for customers to begin evaluating it, we have created ema:Play, a custom piece of hardware so customers can prove their concepts before they take on the task of developing their own custom board to accept ema and bring their IoT product to market.

Development Kit

ema:Play’s onboard microcontroller (MCU) and its Segger JLink® on-board debugger provide a robust environment to assist in your software development efforts. In addition, ema:Play’s multiple interfaces, on-board sensors, and LEDs support a broad range of proof of concept application uses.

Evaluation Platform

OptConnect ema™ comes with a lifetime license for Summit, OptConnect’s cloud management system that enables you to monitor cellular network performance, to track notable events, and to be alerted if the unit loses connectivity.
