TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
SIMCom SIM7020G-SUB KIT offers a quick way to get started with SIM7020G. It lets the designer verify each function of SIM7020G quickly and easily.
The kit includes a USB-MicroUSB cable and an antenna.
SIM7020G is Multi-Band NB-IoT module solution in a SMT format.
This compact module supports NB-IoT in 3GPP release 14 which is also known as NB2.
It has strong extension capability with rich interfaces including UART, GPIO etc. It is designed for applications that need low latency, low throughput data communication in a variety of radio propagation conditions. It is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring, E-health etc.
This document is targeted for customers to understand the differences between SIM7080G and SIM7020X. Users can use SIM7080G or SIM7020X module to design and develop applications quickly.
The SIM7020X series include SIM7020C, SIM7020E and SIM7020G.

What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.
In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.
Recommended kernel configurations to enable are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
Configs for Modem/PPP support:
Configs for USB network drivers:
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.
