SX1278 LORA Module LORA RA-02 LORA Ultra Long Communication Distance With Bottom Plate Not SolderedItem NO.: RA-02

SX1278 LORA Module LORA RA-02

Product Information:

The SX1278 LoRa spread spectrum wireless module adopts the LoRa series module Ra-02 The interface introduced is compatible with the NRF24L01 module. If you want to transmit data over long distances, you can directly replace NRF24L01 by changing the program without changing the hardware design.

LoRa series modules (Ra-01/Ra-02), whose RF chip SX1278 mainly uses LoRa ™ Remote modem, used for ultra long distance spread spectrum communication, has strong anti-interference ability and can minimize current consumption. With LoRa ™ Patented modulation technology, SX1278 has a high sensitivity of over -148dBm, a power output of+20dBm, long transmission distance, and high reliability. Meanwhile, compared to traditional modulation techniques, LoRa ™ Modulation technology also has significant advantages in anti blocking and selection, solving the problem of traditional design schemes not being able to simultaneously consider distance, anti-interference, and power consumption. Ra-01 and Ra-02 operate at a frequency of 433M, mainly targeting regions with a 433M network segment, including China and Southeast Asia.
