Semtech SX1268 LoRa® Transceiver

Semtech SX1268 LoRa® Transceiver is a sub-GHz radio transceiver that offers a best-in-class range for reliable, low data rate, and low power communications. This transceiver is compatible with LoRaWAN® networks with the support for LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The SX1268 transceiver features a simple command-based interface, global frequency coverage, and is available in a 24-pin small size footprint. This transceiver operates at 4.6mA receiving current (RX), 410MHz to 810MHz frequency range, and provides a simple command-based interface for flexible configuration. The SX1268 transceiver is used in applications such as smart meters, agricultural sensors, healthcare, smart city sensors, leak detection, building automation, and predictive maintenance.
