N401AS SX1262 LoRa Module

Overview

N401AS is a ultra-long-range LoRa® RF transceiver module based on the Semtech SX1262 chip. Operates across key Sub-GHz ISM bands (169 MHz, 433 MHz, 868 MHz, and 915 MHz), delivering a powerful +22 dBm output power and an exceptional receiver sensitivity down to -148 dBm. Communication over distances up to 2 km. Full pin breakout, the module offers developers maximum flexibility for creating power-efficient IoT solutions that comply with LoRaWAN® and proprietary protocols.  Full ESD protection on all interfaces.

The N401AS is perfect for a vast array of long-range, low-power IoT use cases, including:

• Smart Agriculture: Soil moisture sensors, weather stations, livestock tracking.

• Smart City & Utilities: Smart street lighting, parking sensors, waste management, water/gas metering (AMR).

• Industrial IoT (IIoT): Asset tracking, supply chain logistics, equipment monitoring, predictive maintenance.

• Environmental Monitoring: Air/water quality sensors, forest fire detection, disaster alert systems.

• Building & Home Automation: Security sensors, HVAC control, energy management.

Development & Integration

• Full Hardware Access: All sx1262 GPIOs, RF, and control pins are broken out.

• Standard SPI Interface: Simple connection to any host microcontroller (e.g., STM32, ESP32, nRF52, Arduino MCUs).

• Software Support: Semtech's LoRaWAN stack and open-source Arduino/PlatformIO libraries for rapid prototyping.

• Design Flexibility: Compact RF design simplifies PCB layout – requires only antenna and host MCU.

Ordering Information

How to Choose?

N401AS: +22dBm, 12mA RX, cost‑effective for meters, sensors, and battery‑critical IoT.

N426AS: +30dBm, 30‑100% longer range, urban‑optimized for smart city, building automation, and interference‑prone applications.

N427AS: +33 dBm for rural, agricultural, and challenging terrain – covers areas where standard modules can't reach.

N428AS: +37 dBm, max range for critical industrial, telemetry, and infrastructure – reliability first, higher power acceptable.
