LoRa Module 433MHz - M5Stack

TheM5StackLoRa module is anintegratedLoRa Ra-02moduledesigned and manufactured by Ai-Thinker.It enables data transmission over long distances, in some areas exceeding the range of up to10 km. High quality of components allows to minimize energy consumption while maintaining transmission precision. Compatible withM5Stackdevelopment modules.

LoRatechnology is used tomodulate the radio signaland is therefore widely used in home automation and IoT. It adjusts the transmitter power and transmission speed to the current propagation conditions, which change depending on the environment, obstacles and reflections.
