The LoRa433_V1.1 Module is a LoRa communication module within the M5Stack stacking module series, operating at a frequency of 433MHz and utilizing the Ra-02 module (chip SX1278) solution. This module comes standard with an external SMA antenna and also reserves two patch MCX antenna socket interfaces, allowing users to freely switch between different types of antennas according to their needs. Additionally, the module features a DIP switch, enabling users to flexibly switch between different communication pins, allowing for the use of multiple stacks simultaneously, offering more customization possibilities and flexibility. It is suitable for applications in remote monitoring, smart cities, home and industrial automation, and Internet of Things (IoT) devices.
