Particle Boron LTE CAT-M1 IoT Development Board (BRN404X)

The Boron includes a pre-provisioned embedded SIM (eSIM). Simply power the board, ensure antenna connection, and it will automatically connect to the Particle Device Cloud using the included free data plan for the first 100 devices. No physical SIM card or carrier activation is required. Device provisioning and data routing are managed entirely through your Particle console.

The Boron is primarily programmed using the Particle Workbench (VS Code extension) or the Web-based Particle IDE, which leverage the Particle Device OS—a real-time operating system built for IoT. You write applications in C/C++ using familiar Arduino-style wiring and APIs. The platform also supports OTA updates, cloud functions, and integrates with webhooks and third-party services like Google Sheets or IFTTT.

Yes, the Boron has a built-in JST PH connector for a single-cell Li-Po battery (3.6-4.2V) and includes charging circuitry. For power efficiency, you can use Particle's sleep modes. In deep sleep (with cellular off), current draw is under 10 μA, preserving battery for months. Active cellular transmission peaks around 80-120 mA. Optimize battery life by keeping the modem in deep sleep and only waking for periodic data transmissions.

The BRN404X variant is certified for LTE CAT-M1 on bands 2, 4, 12, and 13, which are primarily used in North America. Particle offers other regional variants (e.g., Boron 2G/3G) for global coverage. Always verify the specific model number and its supported frequency bands against the cellular networks in your deployment region to ensure compatibility and optimal signal strength.
