LORA RA-02 433MHz
The term LoRa stands for Long Range. It is a long-range, low power wireless platform that has become the de-facto technology for Internet of Things (IoT) networks worldwide.
LoRa is a spread spectrum modulation technique derived from Chirp spread spectrum (CSS) technology.
LoRa was introduced by a company called Semtech.
LoRa modules do come in different frequency ranges, the most common being the 433MHz, 915MHz and 868MHz.
This LoRa technology can be used to transmit bi-directional information to long-distance (in Kms) without consuming much power.
The Ra-02 LoRa module is manufactured by the company Ai-Thinker, the manufacturer of the ESP32S module, the module uses SX1278 IC, works at a frequency of 433MHz.
