SX1278 LoRa Module 10KM Ra-02 Wireless Module

Product details

SX1278 LoRa 433MHz Ra-02 Wireless Module The Ra-02 is a long-range wireless transmission module based on SEMTECH’s SX1278 transceiver. It uses LoRa spread-spectrum technology for reliable communication over distances up to 10,000 metres, with strong anti-interference performance, high sensitivity, and low power consumption. With sensitivity down to -148 dBm and RF output up to +20 dBm (100 mW), it is suited to meter reading, smart-home systems, burglar alarms, remote monitoring, and other long-range wireless projects. Features LoRa spread-spectrum modulation technology Constant RF power output up to +20 dBm (100 mW) Half-duplex SPI communication Supports FSK, GFSK, MSK, GMSK, LoRa and OOK modulation Automatic RF signal detection, CAD mode, and high-speed AFC Packet engine with CRC support up to 256 bytes Compact dual-row stamp-hole package Shielded housing Spring antenna included Specifications Communication distance: Up to 15 km Sensitivity: Down to -148 dBm Programmable bit rate: Up to 300 kbps RSSI dynamic range: 127 dB Wireless frequency: 433 MHz Working voltage: 1.8–3.7 V Working temperature: -40°C to +80°C Arduino Uno / Nano Pinout The module communicates with Arduino through SPI. LoRa Module Pin Arduino Pin MISO Pin 12 MOSI Pin 11 SCK Pin 13 NSS (CS) Pin 10 RESET Pin 9 DIO0 Pin 2 GND GND VCC 3.3 V Important Voltage Note Power the module from 3.3 V. Its logic level is also 3.3 V, so a level shifter is recommended when using a 5 V Arduino.
