Module LoRa868 v1.2 is a LoRa communication module (operating frequency 868MHz) in the M5Stack stackable module series, using the E22-900M22S module (chip SX1262) solution, supporting LoRa™ modulation technology, with stronger anti-interference capability and long-distance communication capability, compliant with FCC, CE, RoHS international standards, and supporting the ISM license-free 868MHz band. The module uses SPI interface for data communication, comes with a default external SMA antenna, and has a DIP switch reserved for flexible switching of communication pins such as NSS, BUSY, RST, IRQ, and supports multiple stacking for simultaneous use, providing more customization possibilities. It is suitable for fields such as remote monitoring, smart cities, smart homes, industrial automation, and IoT devices.
