Description:
Ra-03SCH is a LoRa module developed by Shenzhen Ai-Thinker Technology Co., Ltd. This module is used for ultra-long-distance spread-spectrum communication. Its RF chip LLCC68mainly uses a LoRa™ remote modem for ultra-long-distance spread-spectrum communication. It has strong anti-interference and can minimize current consumption. With SEMTECH's LoRa™patented modulation technology, LLCC68 has a high sensitivity of over -129dBm, a transmit power of +22dBm, a long transmission distance, and high reliability. At the same time, compared with traditional modulation technology, LoRa™ modulation technology also has obvious advantages in anti-blocking and selection, which solves the problem that traditional design schemes cannot take into account distance and anti-interference. and power consumption at the same time.
