M5Stack A152-EU868 Atom DTU LoRaWAN-EU868

M5Stack A152-EU868 Atom DTU LoRaWAN-EU868 is a LoRaWAN programmable Data Transmission Unit (DTU) designed for the 868MHz frequency band and EU868 band. This unit STM32WLE5 solution provides long‑range communication with low power consumption and high sensitivity. The A152-EU868 unit includes a built-in LoRaWAN protocol stack that supports Class A, Class B, and Class C operation modes. This unit supports LoRa® Point‑to‑Point (P2P) communication mode and uses a UART communication interface for flexible configuration.

The A152-EU868 unit features LEGO-compatible mounting holes and a 35mm DIN rail slot at the base. This unit is compatible with UiFlow1, UiFlow2, and Arduino IDE platforms. Typical applications include smart agriculture, industrial monitoring, and environmental monitoring node deployment.
