433MHz SX1278 LoRa Module 10KM Ra-02 Wireless Spread Spectrum Transmission Board

The 433MHz SX1278 LoRa Module (Ra-02) is a high-performance wireless transmission board designed for ultra-long-range communication. Built around the Semtech SX1278 RF chip, it uses LoRa modulation technology to achieve robust, low-power, and interference-resistant data transmission over distances up to 10KM in open environments. Compatible with Arduino, ESP8266, ESP32, and other microcontrollers, it’s perfect for IoT, smart agriculture, remote sensing, and DIY wireless networks.

Features:

• Frequency: 433MHz (ideal for India, China, Southeast Asia)

• Modulation: LoRa, FSK, GFSK, MSK, GMSK, OOK

• Range: Up to 10KM (line of sight)

• Sensitivity: –148dBm

• Power Output: +20dBm (100mW)

• Interface: SPI-compatible, drop-in replacement for NRF24L01

• Antenna: IPEX connector (Ra-02) or spring antenna (Ra-01)

• Voltage: 1.8V to 3.7V DC

Applications: 

• Smart home, IoT, telemetry, robotics, remote control, weather stations
