Detail

Parameters

N427CS High-Power LoRa® RF Module

2 Watts of Punch – Hear Whispers from 15 km Away

Overview

N427CS is a LoRa module based on the SX1261, with discrete PA and LNA. +33 dBm output (2 W), –148 dBm sensitivity, 15 km range in open terrain. Covers 169, 433, 868, 915 MHz ISM bands, LoRaWAN‑compatible.Suited for city‑wide gateways and battery‑powered nodes – water meters, asset trackers – running years on a single cell.

Key Features – What Makes It Different

N427CS delivers +33 dBm and –148 dBm sensitivity on a shielded 4‑layer PCB.
LoRaWAN‑compatible, all SX1261 pins accessible, 10 µA standby.
Reliable RF for gateways and battery‑sensing nodes.
