Key Features
- Semtech SX1278 LoRa Chipset: Industry-standard spread spectrum technology providing robust, interference-resistant communication over extreme distances.
- Up to 10 km Range: Exceptional line-of-sight range with LoRa modulation, far exceeding traditional RF modules like nRF24L01 or HC-12.
- Ultra-High Sensitivity (-148 dBm): Reliably receives weak signals, enabling communication through obstacles, dense urban environments, and challenging terrain.
- Ultra-Low Power Consumption: Sleep current below 1 uA makes it perfect for battery-powered and solar-powered remote deployments lasting months or years.
- Multiple Modulation Modes: Supports LoRa, FSK, GFSK, and OOK modulation for flexible integration with various communication protocols.
- Standard SPI Interface: Easy connection to any microcontroller - Arduino, ESP32, STM32, Raspberry Pi, and more using standard SPI pins.
- Compact SMD Form Factor: Tiny 17x16mm footprint with castellated pads for direct PCB soldering or use with breakout boards.
- Wide Voltage Range (1.8V-3.7V): Operates directly from single-cell LiPo batteries or standard 3.3V regulators without level shifting.
- Industrial Temperature Range: Rated from -40 degreesC to +85 degreesC for reliable operation in harsh outdoor and industrial environments.
- IPEX Antenna Connector: External antenna connection allows use of optimized 433MHz antennas for maximum range and performance.
