Particle by Digi's M635e connectivity module has received Skylo certification, providing IoT device manufacturers with a pre-validated platform for combining terrestrial cellular connectivity with standards-based satellite NTN services.
The M635e integrates global LTE-M, Skylo NTN, dual-band Wi-Fi and Bluetooth Low Energy in a single platform. Devices can use cellular networks for routine higher-throughput communications and automatically fall back to satellite when terrestrial coverage is unavailable, allowing lower-bandwidth information such as alerts, sensor readings and status updates to continue reaching cloud applications.
Certification confirms that the M635e has passed interoperability testing for Skylo's NTN service. Particle is positioning the module as a way to reduce the engineering and certification work required for OEMs developing hybrid cellular-satellite products. Developers can prototype using the company's Muon single-board computer before moving to production, while products incorporating the M635e and specified antenna can also pursue Skylo certification through a product-equivalency process.
Potential applications include asset tracking, agriculture, transportation, industrial monitoring and other IoT deployments where equipment regularly moves beyond cellular coverage. The architecture also allows satellite connectivity to function as a resilience layer rather than the primary network, limiting satellite usage to locations or situations where terrestrial service is unavailable.
The certification marks another step in the expansion of the 3GPP-based NTN device ecosystem, where satellite capability is increasingly being incorporated into conventional cellular IoT hardware rather than requiring dedicated proprietary satellite terminals. For developers, that convergence could make satellite fallback a standard connectivity option within future IoT products rather than a separately engineered communications system.
