Module COMX Cat1
SKU:M031-H
Description
Module COMX Cat1 is an LTE CAT1 data communication module, equipped with the SIM-A7680C module that supports LTE CAT1 frequency bands in China, and supports LTE-TDD/LTE-FDD wireless communication standards. The module integrates an SMA external antenna interface to ensure communication quality and signal stability. It also includes a DC 5 ~ 12V power input interface, providing more power supply options. Compatible with the M5Stack stacking system, it can be stacked with other modules in the series for functional expansion. Compared to NB-IoT, CAT1 offers stronger data transmission capabilities, with a maximum downlink rate of 10Mbps (uplink) / 5Mbps (downlink). This module is ideal for applications requiring data transmission rates, such as remote control and data passthrough.

Power Supply Switching
The module base has a DC power input interface. When using this interface to connect power, strictly adhere to the input range (5-12V) to prevent module damage. The internal power DIP switch can adjust the voltage level of the internal VIN terminal to adapt to different modules.
