B404XMEA

RF Transceiver Modules And Modems Overview

The B404XMEA is a Cellular LTE CAT-1 System-on-Module (SOM) manufactured by Particle Industries, Inc. Designed for IoT applications in North America, it integrates the u-blox SARA-R412M cellular module with the Nordic nRF52840 microcontroller. The module supports AT&T and T-Mobile networks, offering reliable connectivity where Wi-Fi is unavailable. It features a card-edge form factor measuring 42 mm x 30 mm x 5.5 mm, with a maximum operating temperature of +65°C. The hardware includes an integrated antenna connector interface, though the antenna itself is not included.

RF Transceiver Modules And Modems Procurement Notes

Verify that the specific B404XMEA variant matches your target network operator requirements, as compatibility is restricted to supported carriers like AT&T and T-Mobile. Confirm that the external antenna is sourced separately, as it is not included with the module. Ensure mechanical design accommodates the card-edge interface dimensions and thermal constraints up to +65°C. Cross-reference the latest datasheet for pinout definitions and electrical specifications before integration.

RF Transceiver Modules And Modems Selection Notes

Select this module when Wi-Fi coverage is insufficient or unstable for critical IoT deployments. It is appropriate for projects requiring low-power, long-range cellular connectivity without the complexity of full-stack cellular development. Consider the integrated nRF52840 for local processing needs. Evaluate the need for external antennas and ensure the application environment stays within the specified operating temperature range.

RF Transceiver Modules And Modems Part Context

The B404XMEA belongs to the Particle Boron LTE series, designed to bridge existing projects to the Particle Device Cloud. It utilizes the Feather form factor concept adapted for card-edge connections, simplifying integration into custom PCBs. The module leverages established cellular and Bluetooth Low Energy technologies to provide robust, secure communication capabilities for industrial and commercial IoT applications.
