Ra-01 is a wireless transmission module based on SEMTECH’s SX1278 wireless transceiver. It adopts advanced LoRa spread spectrum technology, with a communication distance of 10,000 meters. It has strong anti-interference ability and has the function of air wake consumption. It can cover thousands of people in the district environment, especially suitable for meter reading, smart home, burglar alarm equipment. LoRa series Ra-01 module is designed and developed by AI-THINKER Technology.
The SX1278 RF module is mainly used for long range spread spectrum communications. It can withstand Minimize current consumption. Thanks to SEMTECH’s proprietary LoRa™ modulation technology, the SX1278 has a high sensitivity of -148 dBm with an output power of +18 dBm, a long transmission distance and high reliability.
At the same time, compared with traditional modulation technology, LoRa ™ modulation technology has obvious advantages in anti-jamming and selection, which solves the problem that the traditional design scheme cannot consider distance, interference and power consumption at the same time.
