Description:
Ra-01SCH is a LoRa series module designed and developed by Ai-Thinker Technology. The module is used for ultra-long-range extended frequency communication, and its radio frequency chip LLCC68 mainly uses LoRa™ remote modem, which is used for ultra-long-range extended frequency communication. It has strong anti-interference resistance and can minimize current consumption. With the help of SEMTECH's LoRa™patented modulation technology, the LLCC68 has high sensitivity over 129dBm, + 22dBm transmission power, long-range transmission, and high reliability.
At the same time, compared with the traditional modulation technology, LoRa™ modulation technology also has obvious advantages in anti-blocking and selection, which solves the problem that the traditional design scheme cannot take into account the distance, anti-interference, and power consumption simultaneously
