N455BS LoRa Transceiver Module

Based on Semtech LR2012 – 1.2W High‑Power for Sub‑GHz LoRaWAN Gateways

📌 Product Overview

N455BS is a high‑performance, LoRa transceiver module designed for license‑free long‑range communication. Integrates Semtech's LR2012 chipset with built‑in Power Amplifier (PA) and Low‑Noise Amplifier (LNA), offering +31 dBm (1.2 Watt) output power on both Sub‑GHz (868/915 MHz) bands.

With excellent sensitivity and flexible frequency support, this module is ideal for professional LoRaWAN gateways, private networks, and applications that require seamless operation across both sub‑gigahertz ISM bands.
