GSM Module/4G LTE modem with SIM card socket, SMA antenna connector, DC power jack, and an RS232 interface supports wireless communication modes of LTE-TDD/LTE-FDD/GSM/GPRS/EDGE.
GSM Module 4G SIM7670C with LM317
This board is built around the SIMCOM A7670C LTE module and comes with an RS232 interface. The RS232 interface enables easy connection with the computer or laptop using a USB to Serial connector or to the microcontroller using an RS232 to TTL converter. A 3-pin header also exposes a 1.8V level UART interface for direct interfacing with microcontrollers. Communication with A7670C is done using AT commands.
