Module LoRa433 v1.1
SKU:M005-V11
Description
Module LoRa433 v1.1 is a LoRa communication module (operating at 433MHz) in the M5Stack stackable module series, using the Ra-02 module (chip SX1278) solution. The module comes with a built-in SMA antenna and also provides two additional patch MCX pad interfaces, allowing users to switch between different types of antennas as needed. Additionally, the module features a DIP switch for flexible switching of communication pins, enabling multiple stacked modules to be used simultaneously, offering more customization possibilities and flexibility. It is suitable for applications such as remote monitoring, smart cities, home and industrial automation, and IoT devices.
