Iridium Certus 9704 Developer Kit
The Iridium Certus 9704 Developer Kit is an essential tool for engineers looking to streamline the development of satellite IoT applications. Built around the high-performance Certus 9704 module, the kit provides everything needed to design, test, and deploy IoT solutions that operate reliably in even the most remote environments.
Key Capabilities
All-in-one development platform for evaluating, prototyping and testing Iridium Certus 9704 satellite IoT applications.
Pre-provisioned Iridium Certus 9704 module for faster setup and testing
Iridium Messaging Transport for messages of up to 100 KB
Arduino-based development for rapid application prototyping
Serial, USB and GPIO interfaces for flexible hardware integration
Battery, antenna and MicroSD storage included for field evaluation
The Iridium Certus 9704 module utilizes Iridium Messaging Transport, a message-based service that allows you to transmit data packets of up to 100 kB. 34% smaller than the Iridium 9603N, the 9704 also doubles the speed in which data is sent, and the much larger message size lets you send more data, plus image and audio files.
Utilizing Iridium’s global L-band network, it delivers low latency, truly worldwide coverage, making it ideal for mission-critical applications in industries like transportation, agriculture, energy, and environmental monitoring.
The developer kit includes pre-provisioned hardware, an intuitive software platform, and Arduino compatibility, offering developers a flexible and efficient environment for rapid prototyping and deployment.
