General ISM < 1GHz LoRa™ Transceiver Module 918MHz Antenna Not Included, U.FL Surface Mount
Active

Overview

The LAMBDA68C-9S is a high-performance LoRa transceiver module operating at 918MHz based on the Semtech SX1268 chip. It is designed for long-range wireless communication with a high output power of up to 22dBm and a sensitivity of -148dBm. The module features a shielded SMT design with a U.FL connector for external antenna flexibility.

Why Choose This Part

The module offers an excellent link budget for extreme range while maintaining low power consumption, drawing only 8.8mA in LoRa 125KHz mode. Its integrated shielding and U.FL connector simplify RF certification and antenna integration in compact surface-mount designs.

Applications

Smart Agriculture
Long-range sensor nodes for soil moisture and environmental monitoring in rural areas.
Industrial Telemetry
Remote data acquisition from industrial equipment in environments where cellular coverage is unavailable.
Smart Metering
Reliable data transmission for utility meters through walls and urban obstructions.
