Description:
Ra-01 LoRa Spread Spectrum
Description:
The series of modules RF chip SX1278 mainly uses LoRa ? remote modem for ultra-long distance spread Letter, strong anti-interference, to minimize current consumption. With the help of SEMTECH's LoRa ?Lee modulation technology, SX1278 has a high sensitivity of more than -148dBm, +20dBm power output,Transmission distance, high reliability. At the same time, relative to the traditional modulation technology, LoRa ? modulation technology in the anti-Blocking and selection also has a clear advantage to solve the traditional design can not take into account the distance,Anti-jamming and power consumption problems. Ra-01, Ra-02 operating frequency of 410-525MHz, support for China and Southeast Asia.

Characteristics:
LoRa ? spread spectrum modulation technology
? Ultra-far communication distance of 15KM
? + 20dBm-100mW constant RF power output when voltage changes
? High sensitivity: down to -148dBm

1* SX1278 LoRa Ra-01 Spread Spectrum Wireless Module 433MHz Serial SPI Interface



Ra-02 Module
Description:
Ra-02 is based on SX1278 wireless transparent transmission module (transceiver one), with IPEX socket it can connect external antenna.
Using advanced LoRa spread spectrum technology, communication distance is10000 meters, super error correction, anti-interference ability, with the air wake-up function (ultra-low power consumption). It can be used in the enviroment with thousands of people,especially for meter reading, smart home, burglar alarm and other equipment.
