Description
The M5Stack LoRa Module v1.2 is a dedicated, stackable communication board designed for integrating long-range, low-power LoRa connectivity into IoT systems. At its core is the E22-900M22S module, which leverages the Semtech SX1262 chipset to support LoRa, FSK, and OOK modulation schemes across the 850-930 MHz frequency range. This provides developers with a highly reliable wireless link capable of penetrating urban and rural environments with minimal power consumption.
The module’s architecture is optimized for low-duty-cycle applications, featuring precise power management with sleep currents as low as 26.31 µA and typical receive currents under 3 mA. The inclusion of physical DIP switches allows for on-the-fly hardware reconfiguration of the SPI bus and interrupt pins, simplifying integration with different host controllers and M5Stack cores. The provided SMA antenna connector and included 5 dBi rubber duck antenna ensure optimal RF performance and range for deployment-ready solutions.
