Overview
LoRa Smart Home (LLCC68) is a sub-GHz LoRa® RF Transceiver for medium range indoor and indoor to outdoor wireless applications. SPI interface. Pin-to-pin compatible to SX1262. SX1261, SX1262, SX1268 and LLCC68 are designed for long battery life with just 4.2mA of active receive current consumption. The SX1261 can transmit up to +15dBm and the SX1262, SX1268 and LLCC68 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 for consumer use. The device provides LoRa modulation compatible with Semtech transceivers used by the LoRaWAN® specification released by the LoRa Alliance®. The radio is suitable for systems targeting compliance with radio regulations including but not limited to ETSI EN 300 220, FCC CFR 47 Part 15, China regulatory requirements and the Japanese ARIB T-108. Continuous frequency coverage from 150MHz to 960MHz allows the support of all major sub-GHz ISM bands around the world.

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.
