Sterling™-EWB IoT Module

Overview
A match made for IoT.
New: AT command set firmware and sample applications!
The Sterling-EWB wifi module 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 embedded module 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

Now with Easy-to-Use AT Command Set!
The Sterling-EWB now features an intuitive AT command set for development, configuration and deployment of customer applications for their host MCU. AT commands are an easy and familiar way to develop for both the 802.11 and Bluetooth LE wireless interfaces inside the Sterling-EWB. They use simple commands to configure, connect and send data to the cloud using the Sterling-EWB, with minimal wireless experience needed.
The AT command set dramatically reduces development time with a popular Hayes style interface familiar to many developers and can abstract hundreds of lines of C code into a few simple, pre-programmed functions.
