Ready for an open source IoT platform that transforms IoT development?

Accelerating innovation in your business is easier when you don’t have to start your development from scratch. Legato® open source software and mangOH® open source hardware IoT platforms enable developers to focus on building value-add applications quickly that improve the user experience, operational efficiency, and help businesses take advantage of the IoT.

Legato® Open Source Software

Legato® is the Sierra Wireless Linux-based application framework that enables you to deploy secure applications and maintain Linux distribution in a feature-rich development environment. Released in open source, Legato future-proofs your software investments with the option to port the entire stack and applications over to any application processor. The robust Legato APIs let you connect to any cloud or network, enabling you to focus on building the value-added applications that improve your solution.

Save development time with Legato pre-integrated, tested, and validated inside the application processors of our WP Series modules and FX30 programmable gateways.

mangOH® Reference Design

mangOH® open hardware platforms enable rapid prototyping and faster time-to-market of new IoT applications. Designed specifically for cellular-enabled IoT applications, mangOH boards provide a sensor-to-cloud platform for building industrial-grade products with vetted components, open source software, and a business-friendly open license to modify and reproduce the design.

IoT Connectors

At the heart of Project mangOH are IoT Connectors designed to bring technology interoperability by making it easy to add new combinations of wired, wireless, and sensor technologies. They can be used both in prototyping and in final production with an industrial-grade pluggable form-factor that uses on-board EEPROM to identify itself to the host platform. The interface used is an open standard based on QDFP+ specification that uses a common footprint and pin out.
