Product characteristics:
SX1278 LoRa Spread Spectrum Wireless Module 433MHz Wireless Serial Port UART Interface Ra-01
Ra-01 / Ra-02 series of radio frequency chip SX1278 mainly uses LoRa ™ remote modem for ultra-long distance spread spectrum communication, strong anti-interference, to minimize current consumption. With SEMTECH's LoRa ™ patented modulation technology, the SX1278 has a high sensitivity of more than -148dBm, a power output of + 20dBm, and a high reliability. At the same time, compared with the traditional modulation technology, LoRa ™ modulation technology in the anti-blocking and selection also has obvious advantages, to solve the traditional design can not take into account the distance, anti-interference and power consumption. Ra-01, Ra-02 operating frequency 433M, mainly for the 433M network area, including China and Southeast Asia.
