Yellow Submarine announce availability of IoT Evaluation Kit including access to Machine Learning Platform.

June 14, 2019

The Evaluation Kit includes an Evaluation Board with your choice of 2G/3G or LTE connectivity, a sample IoT sensor (temperature), and all the cellular accessories you need to build your first industrial-grade proof-of-concept

Product Features

A new family of production-grade 2G, 3G, and LTE-enabled hardware that vastly reduces the cost and complexity of deploying cellular-connected IoT solutions at scale.

All modules include the following features:

     - Embedded SIM card, which resists vibration, corrosion, and mechanical failure  
     - Surface-mountable design, for PCB assembly in mass-production
     - Industrial temperature range from -20 to 85C for deployment in hostile environments
     - Pinout with support for 2G, 3G, LTE M1, and future-compatible for NB1
     - Fully certified design virtually eliminating the cost and complexity of RF and carrier compliance

Evaluation Board Features

The Evaluation Kit contains a breakout board which provides easy access to all the pins and peripherals available on all module variants. The Evaluation Board includes:

     - Physical USB access for flashing and serial communications
     - Li-Po battery connector for connecting external batteries
     - Power barrel jack connector for external power
     - MODE and RESET buttons
     - Charge and status LEDs to appreciate device state at a glance

The 2G/3G Evaluation board contains a soldered module, which supports worldwide 2G and 3G connectivity and can be configured into a 2G only mode.

The LTE Evaluation board contains a soldered module, which supports LTE M1 connectivity.
