The first Particle device with cellular, Wi-Fi and satellite NTN connectivity, helping global IoT deployments stay connected beyond terrestrial network coverage

Particle by Digi, a division of Digi International, today announced that Particle M635e has achieved Skylo certification, giving IoT developers and enterprises a validated path to extend connected IoT solutions beyond the reach of terrestrial cellular networks.

The device combines Skylo’s satellite-based Non-Terrestrial Network (NTN) with global LTE-M cellular, dual-band Wi-Fi and Bluetooth Low Energy (BLE) connectivity, delivering the best of both worlds. Cellular connectivity provides low-latency, high-throughput communication for routine data transmission, over-the-air firmware updates and real-time fleet management. When devices move beyond cellular range, the M635e automatically falls back to satellite, ensuring mission-critical alerts, sensor data and status updates reach the cloud without interruption. Together, cellular and satellite connectivity eliminate dead zones, reduce the risk of data loss in remote deployments and give operators consistent visibility across their entire fleet, whether the assets are in a city, a farm or the open road.

Skylo certification confirms that a device, module or platform has been tested and validated for interoperability with Skylo’s standards-based NTN service. By expanding the ecosystem of certified devices, developers, OEMs, carriers and enterprise customers build and deploy NTN services with greater consistency and enhanced user experiences.

“Satellite connectivity has long been the missing piece for truly global IoT deployments. With the Particle M635e achieving Skylo certification, we’re giving developers a production-ready path to build devices that work everywhere, not just where cellular towers exist. This is a meaningful step in the Particle by Digi mission to simplify connected product development at scale,” said Mike Rohrmoser, Vice President, Particle by Digi.

Operating on the Particle platform, the M635e can help compress the timeline from development to market. With Skylo certification completed, customers building on it have a validated connectivity platform that has been tested for interoperability with Skylo’s NTN service. Developers can prototype with a Particle Muon single-board computer and move toward production with confidence that compliance, carrier acceptance and NTN interoperability have already been verified. This pre-certified path reduces development cycles, lowers certification costs and eliminates a significant source of launch risk, helping teams bring connected products to market faster. OEMs integrating the Particle M635e and the supplied antenna can also apply for their own Skylo Certification, typically at no-cost, through a product-equivalency process.

“Every device added to the Skylo certified ecosystem makes standards-based connectivity easier to adopt. The Particle by Digi M635e gives OEMs a production-ready path to integrate cellular and satellite connectivity into IoT products, helping extend the reach and resilience of connected services beyond terrestrial networks,” said Karthik Ranjan, IoT Partnerships Leader at Skylo Technologies.
