Telemetry Wireless LoRa Ra-02 SX1278 433MHz SPI

SX1278 LoRa spread spectrum wireless module adopts Anxinke LoRa series module Ra-02. The interface is compatible with NRF24L01 module. If you want to transmit data over a long distance, you can directly replace NRF24L01. Just change the program and you don’t need to change the hardware design.

Anxinke LoRa series modules (Ra-01/Ra-02) are designed and developed by Anxinke Technology. The radio frequency chip SX1278 of this series of modules mainly uses LoRa™ remote modem for ultra-long-distance spread spectrum communication. It has strong anti-interference and can Minimize current consumption. SEMTECH patented by the modulation LoRa ™ technology, SX1278 having high sensitivity than -148dBm, the output power of + 20dBm, the transmission from the stay away, and high reliability. At the same time, compared with traditional modulation technology, LoRa™ modulation technology also has obvious advantages in terms of anti-blocking and selection , which solves the problem of distance, anti-interference and power consumption that traditional design schemes cannot simultaneously take into account . Ra-01, Ra-02 work frequency 433M, mainly for the 433M network segment area.
