M5Stack ATOM DTU NB-IoT Kit Global Version (SIM7020G)

Description

• M5Stack ATOM DTU NB-IoT Kit Global Version (SIM7020G)
• Offers a programmable data transmission unit
• Built-in SIM7020G module
• Integrates NB-IoT communication functions
• Suitable for various low-latency, low-throughput application
• Communication interface: RS485

The M5Stack ATOM DTU NB-IoT Kit Global Version (SIM7020G) is a programmable data transmission unit (DTU) that integrates NB-IoT communication functions. The built-in SIM7020G module covers most of the Cat-NB frequency bands and integrates the SMA external antenna interface to improve the communication quality and signal stability of the device.

The ATOM DTU series adopts a more open architecture design. The controller ATOM LITE can modify the program at will according to the actual business, and the whole machine reserves a variety of interfaces (RS485, I2C, custom interface) for users to expand, which is convenient for the rapid access of sensors and actuators.

ATOM DTU NB is very suitable for various low-latency, low-throughput application scenarios (such as remote control, asset tracking, remote monitoring, remote medical treatment, shared bicycles, etc.).
