Boron’s embedded SIM and Particle SIM support global LTE-M coverage in 100+ countries, with automatic carrier selection via Particle’s managed network agreements. The onboard nRF52840 handles application logic, BLE device pairing, and sensor interfacing while the separate modem manages cellular connectivity independently for clean power management. Particle Device OS abstracts RTOS complexity, exposing a simple C++ API for cloud publish/subscribe, OTA firmware updates, and device diagnostics. Particle’s cloud console provides real-time device health, event streams, and integration webhooks to AWS, Azure, and Google Cloud. Pin-compatible with the Feather ecosystem, enabling rapid hardware prototyping with hundreds of ready-made wings.
