Overview

The HJ-68LR(68)-P400 is a compact, ultra-low power LoRa transceiver module designed for the 410MHz to 470MHz frequency band. It enables long-range wireless communication with high interference immunity while maintaining a deep sleep current of approximately 1uA.

Why Choose This Part

This module features an extremely low power footprint, consuming less than 1uA in sleep mode, making it suitable for battery-operated deployments. It offers a robust 20dBm transmit power to overcome path loss in challenging RF environments.

Applications

Smart Utility Metering
Ideal for wireless reading of water, gas, and electricity meters in industrial or urban environments where long range is required.
Industrial Remote Control
Used in wireless POS machines and industrial control systems requiring reliable data transmission across large facilities.
Home Automation
Enables long-distance remote control and sensor networking within smart home ecosystems.
