Electronic module 433mhz Sx1278 Lora Module Ra-02 Wireless Spread Spectrum Transmission Board 2.4G IPX Antenna Smart

Anxinke Lora Series Module (Ra-01/Ra-02) Was Designed and Developed by Anxinke Technology. the RF Chip Sx1278 of This Series Module Mainly Uses Lora?? Remote Modem Is Used for Ultra-Long Distance Spread Spectrum Communication, Which Has Strong Anti-Interference and Can Greatly Reduce Current Consumption. with the Help of Semtech LoRa?? Patented Modulation Technology, Sx1278 Has High Sensitivity over-148dbm, + 20dBm Power Output, Long Transmission Distance and High Reliability. at the Same Time, Compared with Traditional Modulation Technology, Lora?? Modulation Technology Also Has Obvious Advantages in Anti-Blocking and Selection, Which Solves the Problem That the Traditional Design Scheme Cannot Give Consideration to Distance, Anti-Interference and Power Consumption at the Same Time. Ra-01,Ra-02 Working Frequency Is 433M, Mainly for Areas with 433M Network Segment, Including China and Southeast Asia.
