M5Stack A152-US915 Atom DTU LoRaWAN-US915

M5Stack A152-US915 Atom DTU LoRaWAN-US915 is a LoRaWAN programmable Data Transmission Unit (DTU) designed for the 915MHz frequency band. This unit is ideal for regions using the US915 band. The A152-US915 unit employs the STM32WLE5 solution to support long-range communication with low power consumption and high sensitivity. This unit uses a rubber-duck antenna to deliver stable coverage. The A152-US915 unit includes a built-in LoRaWAN protocol stack that supports Class A, Class B, and Class C operating modes. This unit supports LoRa® Point-to-Point (P2P) communication mode. The A152-US915 unit features a 35mm DIN rail slot at the base to allow direct installation on industrial rails. Typical applications include smart agriculture, industrial monitoring, and environmental monitoring node deployment.
