433Mhz RA-01 LoRa Wireless Transmission Module
Ra-01 LoRa SX1278 433mhz Wireless Spread Spectrum Transmission Module Ultra-long Distance Spread Wireless Serial SPI Interface. Radio frequency chip of LoRa series module SX1278 mainly adopts LoRa remote modem for ultra long-distance spread spectrum communication, which has strong anti-interference and can minimize current consumption.
SX1278 has a high sensitivity of over -148dBm and a power output of +20dBm
The transmission distance is long and the reliability is high. At the same time, compared to traditional modulation techniques, LoRa modulation technology is resistant.
Blocking and selection also have obvious advantages, which solves the problem that traditional design solutions cannot take into account the distance at the same time.
Anti-jamming and power consumption issues. Ra-01, Ra-02 operating frequency 433M, mainly for the 433M network segment, including China and Southeast Asia.
