Elecrow nRFLR1121 Wireless Transceiver Module w/ nRF52840 & SX1121

Description

The Elecrow nRFLR1121 Wireless Transceiver Module is a high-performance, system-on-module solution engineered for demanding IoT applications requiring both local mesh networking and long-range, low-power telemetry. Its core integrates the powerful ARM Cortex-M4 based nRF52840, handling Bluetooth 5.3, Zigbee, Thread, and NFC protocols, with the Semtech SX1121 transceiver dedicated to sub-GHz LoRa and LR-FHSS satellite communication. This dual-chip architecture provides unparalleled flexibility for hybrid network topologies.

Designed for extreme environments and energy efficiency, the module operates from -40°C to +85°C and features deep sleep currents as low as 6μA, making it ideal for solar-powered or battery-backed field deployments. With a compact 20x20x3.5mm LGA package, it delivers up to +20dBm transmit power and -141dBm receiver sensitivity, ensuring robust connectivity over distances up to 10 kilometers. It is a foundational building block for industrial telemetry, smart agriculture, asset tracking, and remote environmental monitoring systems.
