SX1278 LoRa Ra-02 Module 433MHz Spread Spectrum Transceiver
The SX1278 LoRa Ra-02 module is a long-range, low-power wireless transceiver operating in the 433MHz ISM band, based on Semtech’s SX1278 chip. It features LoRa spread spectrum modulation for robust communication up to 10km and is interfaced via SPI for integration into Arduino, ESP32, or Raspberry Pi projects.
Features
- Long-range LoRa communication up to 10km with +20dBm (100mW) output power and -148dBm high sensitivity.
- Multi-modulation support for FSK, GFSK, MSK, GMSK, LoRa, and OOK, programmable via SPI interface.
- Low power operation with 2.5-3.7V supply range and air-wakeup function for battery-powered IoT nodes.
- Robust RF performance with 127dB dynamic RSSI range, automatic signal detection, and CRC packet engine.
- Compact SMD footprint with IPEX antenna connector and shielded metal case for stable deployment.

The SX1278 LoRa Ra-02 module is a dedicated wireless transceiver designed for long-range, low-data-rate IoT communication. Built around the proven Semtech SX1278 RF IC, it implements LoRa spread spectrum modulation to achieve exceptional link budget and interference immunity, making it ideal for challenging urban and rural environments. The module operates in the 433MHz frequency band, offering a balance of range and antenna size.
Communication is handled via a half-duplex SPI interface, allowing for direct connection to microcontrollers like STM32, ESP32, or ATmega328P (Arduino). Its integrated packet engine with CRC supports reliable data frames up to 256 bytes. The module’s shielded metal housing ensures stable RF performance and protects against external noise, while the IPEX connector allows for the attachment of external antennas to optimize range for specific deployments.
