COM.CAT1

SKU:M031-H

Description

COM.CAT1 is an LTE CAT1 data communication module with a built-in SIM-A7680C module for LTE CAT1 in China, it supports LTE-TDD/LTE-FDD wireless communication. The module integrates SMA external antenna interface to stabilize the communication quality and signal of the device. Integrated DC 5/12V power input interface, provide more power supply options. It can be stacked with the same series of M5 stacking modules to extend the functions. In comparison with NBIoT, CAT1 has a stronger data transmission speed. The maximum downlink rate is up to 10Mbps (uplink) / 5Mbps (downlink). This module is ideal for applications that require data transmission rates (remote control/data transit, etc.).
