868Ｍ LoRa transceiver SX1262 Arduino RF module

N401AS RF module based on SX1262 transceiver, designed for 169M, 433M, 868M and 915 MHz LoRa band. Up to +22 dBm output power and down to -148 dBm sensitivity. The N401AS Arduino LoRa module support Arduino. spi port.

The SX1262 module's used SMD package, it antenna port( RF pin ) is matched to 50 Ohm impedance well. Users needn't to design RF circuit. And user needn't to spend time to choose suitable antennas.   

N401AS operates at 1.8~3.6V voltage and very low current which makes the RF modules suitable for battery-powered. The module leads all pins out of SX1262 for secondary development.

N401AST adopts ±1 ppm TCXO which makes it possible to use narrower bandwidth to achieve the high sensitivity up to -148 dBm.

SX1262 transceiver Description

SX1261 and SX1262 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4.2 mA of active receive current consumption. The SX1261 can transmit up to +15 dBm and the SX1262 can transmit up to +22 dBm with highly efficient integrated power amplifier.s. These devices support LoRa® modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements utilizing the global LoRaWANTM standard or proprietary protocols. The devices are designed to comply with the physical layer requirements of the LoRaWANTM specification released by the LoRa AllianceTM. The radio is suitable for systems targeting compliance with radio regulations including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements and the Japanese ARIB T-108. Continuous frequency coverage from 150 MHz to 960 MHz allows the support of all major sub-GHz ISM bands around the world.

N401AS SX1262 Arduino library

Arduino library to use Semtech SX126x LoRa chips and modules to communicate
This library is for LoRa communication with Semtech SX126x chips. It is based on Semtech`s SX126x libraries and adapted to the Arduino framework for ESP32, ESP8266, Nordic nRF52832 and Raspberry RP2040. It will not work with other uC`s like AVR.
