Product Features

    l  Excellent hardware design

    Maipu STR880-1SR intelligent 5G gateway adopts ultra-small size design, and the overall size is only 58mm×52mm×22mm (length × depth × height). Its weight is only 79g, working temperature can reach -25~65, maximum power is only 5W, low heating, high reliability, very suitable for installation in UAV control, self-service terminal, outdoor monitoring and other complex environment.

    l  High-performance 5G network platform

    The built-in 5G module supports NR (Sub6G), TDD-LTE, FDD-LTE and 3G network modes, and supports eSIM and Nano-SIM card modes, providing flexible and stable mobile network access and ensuring network interconnection.

    l  Rich external interfaces

    It has a GE Gigabit interface, an RS232 and two UART serial ports and a USB 3.0 OTG interface. The serial port supports multiple mode protocols, such as transparent transmission, MQTT and Modbus. It can be flexibly adapted to the control of the UAV 5G flight, real-time data returning of auto terminal, acquisition of unmanned monitoring station information, and other application scenarios.

    l  Rich software functions

    Support IPv4, IPv6, MQTT, DHCP, and other common protocols; support IPsec encryption tunnel, ensuring the data security; support auto detection of device faults, and auto reboot.
