## Overview

The Allianztec SX1278 LoRa Module is a compact, high-performance 433MHz transceiver designed for ultra-long range wireless communication up to 10km. Featuring +20dBm output power, exceptional sensitivity (-139dBm), and ultra-low power consumption (0.2µA sleep mode), it’s perfect for smart home and industrial IoT projects. Its breakout board with SPI interface and Arduino library compatibility ensures rapid prototyping and seamless integration.

## Description

The SX1276/77/78/79 transceivers feature the LoRa long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. As the SX127x chips needs a few additional components for operation, the Ra-02 module developed by A.I. Thinker includes an SX1278 and everything needed for it to work in a small form factor PCB. This breakout board facilitates developing/prototyping with the Ra-02 module tremendously. Solder the pins, plug it into a microcontoller/SoC using dupont wires or a solderless breadboard, and use it to create LoRa projects! Features: Wireless Standard: 433MHz Frequency range: 420~450MHz +20dBm@10mW. Stable RF output power when input voltage changed Half-duplex SPI communication Programmable bit rate can reach to 300kbps 127dB RSSI wave range Radio: Semtech SX1278 Antenna connector: IPX (U.FL) Operating Voltage: 1.8~3.7VDC, default 3.3V Working Current: Rx <10.8mA (LnaBoost closed, Band 1) Tx <120mA (+20dBm); sleep mode: 0.2uA
