Sterling-EWB IoT Module

Recommended for New Design (RND)

Overview

A match made for IoT.

The Sterling-EWB is a simple, secure, reliable way to gather meaningful IoT intelligence. It’s easier than ever to gather sensor data and wirelessly send it to cloud services like Amazon AWS. Available as an ultra-compact SiP and as a PCB module (chip antenna or U.FL connector), it's a comprehensive IoT platform in a cost-effective package.

  • A Full Hostless Platform - High performance STM32F412 Cortex M4
  • Power Conscious - Light power usage for long life on battery power
  • Multiple form factors - including all-in-one chip antenna module
  • Rugged Design - Supports industrial temperatures from -40°C to +85°C
  • Enterprise Security - WPA/WPA2, AES, TKIP, and more
  • Personal Support - Free antenna scans, design reviews, on-site EMC support and global FAEs / Tier 2 Support
