The SIMCom SIM7070 Series_TE Kit is a comprehensive solution designed for testing and developing applications with SIMCom's SIM7070 series modules. This kit facilitates rapid prototyping and evaluation of the SIM7070 module's capabilities, particularly in the context of AIoT (Artificial Intelligence of Things) applications, as indicated by the "a SUNSEA AIoT company" tagline.

Function Description:

The SIM7070 Series_TE Kit primarily serves as a test and evaluation platform for the SIM7070 module. It allows users to:

Interface with the SIM7070 module: The kit includes a Test Extension (TE) board that houses the SIM7070 module, providing necessary connectors for power, data, and antennas.
Communicate via USB: A Micro USB connector (labeled 'C' on the TE board) enables communication with a host PC, facilitating data transfer, AT command interaction, and driver installation.
Connect Antennas: Dedicated connectors for GNSS (Global Navigation Satellite System) antenna (labeled 'D') and Main Antenna (labeled 'E') allow for testing cellular and positioning functionalities.
Integrate with an EVB Board: The TE board is designed to be installed onto a SIMCom EVB (Evaluation Board) for a more complete testing environment. This modular approach allows users to leverage the broader functionalities and peripherals offered by the EVB.
Utilize AT Commands: The kit supports interaction with the SIM7070 module using AT commands, which are standard for controlling cellular modules. SIMCom provides a dedicated "Serial Port Tool" for sending and receiving AT commands, logging communications, and managing command lists.
Driver Installation: The kit requires specific USB drivers to be installed on the host PC to recognize the SIM7070 module's various functionalities (AT command port, diagnostics port, NMEA output port).

Important Technical Specifications:
