T SoM: The heart of your asset tracking solution

T SoM is a powerful, configurable, and extensible IoT System-on-Module (SoM) that provides a MCU, GNSS, and advanced peripherals in a compact form factor. T SoM works out-of-the-box with the Particle Tracking Services software suite that provides location, configuration, and edge application services to all Particle Tracker devices. Together, T SoM and Particle Tracking Services provide an accelerated starting point to organizations that require a tailored tracking solution for sophisticated applications as well as a fully-certified foundation for original equipment manufacturers developing commercial products.
