LoRa Smart Home module (based on Semtech LLCC68)
Frequency band : 868MHz
LoRa Smart Home (LLCC68) is a sub-GHz LoRa® RF Transceiver for medium range indoor and indoor to outdoor wireless applications. SPI interface. Designed for long battery life with just 4.2 mA of active receive current consumption. The LLCC68 can transmit up to +22 dBm 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®.
13mm x 19mm stamp package for easy assembly and low-cost pcb design. For more information you can consult the datasheet of the LLCC68 module on the Semtech website.
