Learn

Before using Unit Cat1-CN, please make sure that a Nano-SIM card supporting LTE Cat1 network (from China Mobile, China Unicom, China Telecom, etc.) has been inserted and that data service is activated. The Nano-SIM card slot is located inside the module. Use a hex screwdriver to remove the three screws on the bottom of Unit Cat1-CN, then flip and remove the bottom cover. The card slot location is shown in the red box below:

Baud Rate Limit
The recommended maximum UART baud rate for the Unit Cat1-CN module is 460800. If configured to 921600, data loss or communication anomalies may occur due to the excessive speed; therefore, such configuration is not recommended.
