Description The LoRaWAN EU868 module adds long-range, low-power sub-GHz networking to M5Stack Core projects. It uses the RAK3172-8-SM-I solution with an integrated STM32WLE5 wireless MCU, 256 KB Flash, and 64 KB RAM, making it suitable for EU868 LoRaWAN deployments in Europe and other regions using the 863 to 870 MHz band. The LoRaWAN EU868 module supports LoRaWAN 1.0.3, Class A, Class B, Class C, OTAA and ABP activation, UART control through AT commands, and LoRa point-to-point communication. With low-power sleep behavior, DIP-switch-selectable bus pins, stackable module design, and a high-sensitivity rubber duck antenna, it is well suited to remote sensor nodes and long-endurance IoT systems.
