Product Descriptions
Ra-01SCH-P is a LoRa series module. This module is used for ultra long distance spread spectrum communication, and its RF chip LLCC68+mainly uses LoRaT remote modem for ultra long distance spread spectrum communication. It has strong anti-interference ability and can greatly reduce current consumption. With the help of SEMTECH's LoRaTM patented modulation technology, the module is equipped with power amplifier (PA) and low noise amplifier (LNA), with high sensitivity exceeding -137dBm and transmission power of+29dBm. It has a long transmission distance and high reliability. Meanwhile, compared to traditional modulation techniques, LoRaTM modulation technology also has significant advantages in anti blocking and selection, solving the problem that traditional design schemes cannot simultaneously consider distance, anti-interference, and power consumption. It can be widely used in automatic meter reading, home building automation, security systems, remote irrigation systems, etc.
