Module13.2 LoRa-1262
SKU:M149
Description
Module13.2 LoRa-1262 is a stackable long-range LoRa communication module. The module integrates the Stamp LoRa-1262 communication module and adopts the SX1262 LoRa RF transceiver solution, supporting 868 ~ 923 MHz frequency band communication. The module features an RP-SMA external antenna interface; the LoRa communication part uses an SPI communication interface to exchange data with the main controller, and integrates the M5IOE1 IO expansion chip, which can perform reset, bypass, and power management on the LoRa module, effectively reducing overall power consumption. Multiple onboard DIP switches are used for LoRa communication pin switching and M5IOE1 I2C address modification, allowing flexible adaptation to the IO resources of different controllers and supporting multi-module stacking. It is suitable for scenarios such as remote monitoring, smart home, industrial automation, and IoT nodes.
