M5Stack Atom DTU LoRaWAN Kit (ASR6501) comprises a programmable Data Transmission Unit (DTU) suitable for 915MHz frequency. The module adopts the ASR6501 scheme that supports long-distance communication, ultra-low power consumption, and high sensitivity. The kit includes the Atom DTU LoRaWAN915 module, SMA antenna, SMA red cap, M2 hexagon wrench, M2x16 screws, and 3.96-4P terminal. The ATOM DTU series adopts a more open architecture design and superior anti-interference ability to work normally in complex interference environments. Typical applications include automatic remote meter reading, intelligent traffic intelligent parking lot, remote irrigation, and environmental monitoring.
