4G / 3G / 2G / GSM / GPRS / GNSS HAT for Raspberry Pi

he SIM7600E-H 4G HAT is a 4G/3G/2G communication and GNSS positioning module, which supports LTE CAT4 up to 150Mbps for downlink data transfer and it is pretty low power consumption. In simple words, this HAT (for Raspberry Pi) supports cellular communication such as SMS and also data for Internet, and built-in positioning sensor which is GNSS. Sometimes it is called GSM module.

You can connect this 4G module with computer to surf the Internet, or attach it onto Raspberry Pi to enable functions like 4G high speed connection, wireless communication, making telephone call, sending SMS, global positioning, etc.

Note: It does not comes with Raspberry Pi board and SIM card, please get it separately.
