CAT1 SIM7600G 4G with GPS Communication Module

The Gravity communication module with the SIMCom SIM7600G (TEL0161) connects microcontrollers and single-board computers to the mobile network via 4G LTE Cat 1: up to 10 Mbit/s download and 5 Mbit/s upload. In addition there is satellite positioning via GPS, BeiDou and GLONASS. It is controlled with AT commands via UART; on a Raspberry Pi, LattePanda or PC it also works as a network card via USB-C. Microphone and audio amplifier are built in, so besides data also SMS and calls are possible.

Switzerland: 2G (GSM) has been switched off in Switzerland, and the 3G networks are being switched off (OFCOM, as of December 2025). Here the module connects via LTE. Without 2G and 3G, voice calls are only possible via VoLTE.

Important: When the module is operated via the UART connector (PH2.0), it needs an external supply of 5 V to 12 V at the screw terminal. Via USB-C it is supplied with 5 V.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.
