Module LoRa868 v1.2
Description
Module LoRa868 v1.2 is a LoRa communication module (operating at 868 MHz) in the M5Stack stackable module series. It uses the E22-900M22S module (chip SX1262) and supports LoRa™ modulation technology, offering strong anti-interference performance and long-range communication. It meets FCC, CE, RoHS international standards and operates in the ISM license-free 868 MHz band. The module communicates via SPI interface, comes with an external SMA antenna, and features DIP switches for flexible selection of NSS, BUSY, RST, IRQ lines, supporting multiple stacks simultaneously for greater customization. Ideal for remote monitoring, smart cities, smart homes, industrial automation, IoT devices, and other applications.
