Wireless LoRa Module 433Mhz/868Mhz/915Mhz High Sensitivity (-129dBm) LLCC68

DL-LLCC68-S RF module has high receiving sensitivity of -129dBm@LoRa, ultra-low receiving current and dormant current, the transmit power can be configured through software, and the maximum power can reach +22dBm. Compared with traditional modulation technology, LoRa™ modulation technology has obvious advantages in anti-blocking and selection, which solves the problem of distance, anti-interference and power consumption that traditional design schemes cannot take into account at the same time.

433MHz/868MHz/915MHz Wireless LoRa Transceiver Module with LLCC86 Chip 


DL-LLCC68-S is a wireless module designed based on Semtech's radio frequency chip LLCC68. It mainly adopts a new generation of LoRa™ modulation technology for ultra-long-distance spread spectrum communication. This LoRa module is compact in size, and has the characteristics of ultra-low receiving power consumption, strong anti-interference ability, and longer transmission distance than traditional modulation methods. It can be widely used in various wireless communication fields of the Internet of Things.


DL-LLCC68-S RF module has high receiving sensitivity of -129dBm@LoRa, ultra-low receiving current and dormant current, the transmit power can be configured through software, and the maximum power can reach +22dBm. Compared with traditional modulation technology, LoRa™ modulation technology has obvious advantages in anti-blocking and selection, which solves the problem of distance, anti-interference and power consumption that traditional design schemes cannot take into account at the same time.
