SIM7670C 4G LM137 with Antenna(GSM 4G Foldable)

SIM7670C 4G LM137 with Antenna(GSM 4G Foldable)- ADIY
The ADIY 4G LTE modem is equipped with a SIM card socket, an SMA antenna connector, a DC power jack, and an RS232 interface. It supports various wireless communication modes including LTE-TDD, LTE-FDD, GSM, GPRS, and EDGE.

This board is centered around the SIMCOM A7670C LTE module and is furnished with an RS232 interface. The RS232 interface allows for effortless connectivity to a computer or laptop using a USB to Serial connector, or to a microcontroller using an RS232 to TTL converter. Additionally, a 3-pin header provides access to a 1.8V level UART interface, enabling direct interfacing with microcontrollers. Communication with the A7670C module is achieved through the utilization of AT commands.
