Long-Range RF Wireless Module LoRa SX1278 operating at 433 MHz

The XL1278 wireless module is a product of advanced SEMTECH technologies. It leverages LoRa™ modulation technology to offer superior long-range communications over a wide spectrum, with excellent interference resistance and low power consumption. Besides traditional GFSK modulation, the LoRa wide-spectrum technology is employed to enhance performance in challenging environments.

Key Features:

• Supports FSK / GFSK and LoRa™ spread spectrum modulation
• Half-duplex communications
• Superior performance against interference (Channel rejection ratio: 56 dB)
• High reception sensitivity up to -139 dBm (32M negative crystal 10 ppm)
• +20 dBm power output for extremely long-range communications
• Open transmission range up to 5 km
• Operates in the license-free ISM range (433 MHz)
• Supports multiple frequencies and data rates (suitable for FDMA and FM technologies)
• Low power consumption: Reception current: 10-12 mA
• 256-byte FIFO for transmission/reception
• Built-in Received Signal Strength Indicator (RSSI) for channel detection
• Operating modes: FIFO mode / Direct mode (FIFO recommended)

Advanced Features:

• AFC, Air Wake-up, Carrier Sense, FEC Error Correction, AEC Encryption
• Smart reset, low voltage monitoring, timer wake-up, and sleep mode for low power usage
