Note: The SKU with A120 does not include the Atom-Lite host.
Description
Atom DTU Cat1 is a programmable LTE CAT1 data transmission unit (DTU). It comes with a SIM-A7680C module that supports LTE CAT1 bands in China, compatible with LTE-TDD/LTE-FDD wireless communication standards. Compared to NB-IoT, CAT1 offers stronger data transmission capabilities, with maximum downlink speeds of up to 10Mbps (uplink) / 5Mbps (downlink). It features an integrated SMA external antenna interface to enhance communication quality and signal stability. Unlike typical DTUs that only support data passthrough, the Atom DTU Cat1 series adopts a more open architecture design. The Atom-Lite controller allows users to modify the program according to actual business needs, and the device is equipped with multiple interfaces (RS485, I2C, custom interfaces) for user expansion, facilitating quick integration of sensors and actuators. It includes a rail-mounting structure, making it perfect for embedding into various industrial control environments. It is highly suitable for applications requiring higher data transmission rates (remote control/data passthrough, etc.).
