Overview
SX1261, SX1262 and SX1268 sub-GHz radio transceivers are ideal for long range wireless applications. Both devices are designed for long battery life with just 4.2 mA of active receive current consumption. The SX1261 can transmit up to +15dBm and the SX1262 and SX1268 can transmit up to +22dBm with highly efficient integrated power amplifiers.
These devices support LoRa® modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements utilizing the global LoRaWAN® standard or proprietary protocols.
The devices are designed to comply with the physical layer requirements of the LoRaWAN specification released by the LoRa Alliance®.
The SX1268 is suitable for systems targeting compliance with Chinese regulatory requirements, and runs in the 410 – 810 MHz range.

The devastation caused by wildfires makes headlines every year and continues to worsen. Wildfires cause not only enormous humanitarian and economic hardship but also have a massive environmental impact. In addition to destroying animal and plant life, wildfires emit between 5 and 30 tons of carbon per hectare. All of the land that burns globally in an average year adds 13 billion metric tons of additional carbon to the atmosphere annually, a significant contribution to climate change.
