Ra-01 LoRa Module SX1278 433MHz Ra-01
The SX1278 LoRa spread spectrum wireless module uses the LoRa series module Ra-02. The interface is compatible with the NRF24L01 module. If you want to transfer data over long distances, you can directly replace the NRF24L01. Just change the program and do not need to change the hardware design.
Description:
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 operating frequency 433M, mainly for the 433M network segment, including China and Southeast Asia.
