M5Stack LoRa Module (433MHz) v1.1OpenELAB

Description

The LoRa433_V1.1 Module is a part of the M5Stack stackable module series and is a LoRa communication module operating at a frequency of 433MHz, utilizing the Ra-02 module (SX1278 chip) solution. This module comes with a default external SMA antenna and also features two additional patch MCX pad interfaces, allowing users to switch between different types of antennas based on their needs. Additionally, the module is equipped with a dip switch, enabling users to easily switch between different communication pins. It supports multiple stackable uses simultaneously, offering more customization and flexibility. It is suitable for remote monitoring, smart cities, home and industrial automation, IoT devices, and more.

FAQ

Use LoRa Module 433/868 V1.1 DIP switch to change IO to compatible with different controllers.

When the LoRa Module 433/868 V1.1 stack with different controllers, the SPI pins and RST, IRQ, and NSS are different, if some IO used another module or sensor, you could through the DIP switch to change the LoRa Module IO connection, you need to modify the pins define in the program: about the DIP switch and pins definition, you could refer to the documentation: https://docs.m5stack.com/en/module/Module-LoRa868_V1.1
