N401AS SX1262 LoRa Module
Product Overview
The N401AS is a versatile, ultra-long-range LoRa® RF transceiver module based on the renowned Semtech SX1262 chip. Engineered for global deployment, it 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. This combination enables reliable communication over distances up to 2 km, making it an ideal foundation for LPWAN applications. With its compact size and full pin breakout, the module offers developers maximum flexibility for creating power-efficient IoT solutions that comply with LoRaWAN® and proprietary protocols.
Key Features & Benefits
