ADIY GSM SIMA7670C 4G Breakout Board with logic level V1.2

The SIM A7670C 4G LTE breakout Board is a Cat 1 module that supports wireless communication
modes of LTE-TDD/LTE-FDD/GSM/GPRS/EDGE. It supports a maximum 10Mbps downlink
rate and a 5Mbps uplink rate It supports a maximum 10Mbps downlink rate and a 5Mbps uplink
rate. This board features a serial interface and is based on the SIMCOM A7670C LTE modem.
The serial interface allows for simple communication with a computer or laptop via a USB to
Serial adapter or TTL converter. AT instructions are used to communicate with the A7670C. The
SIM A7670C 4G LTE Development Board is designed keeping in mind the requirements of the
user. It has various pinouts from the module, such as RING – used to detect incoming calls, DTR – to use the 4G Module in ultra-low power sleep mode, NET LIGHT – in case the developer wants
to use external LED to indicate network status, RESET – developer can use this pin to connect
with MCU and reset the module if required.
This SIM A7670C 4G breakout Board has a UFL connector, which allows connection of any
antenna with this board. Apart from this, the module is very compact in size. It can be easily
embedded in any customized PCB.
The SIM A7670C 4G Breakout Board supports multiple built-in network protocols likeTCP,
MQTT, HTTP, HTTPS, FTP, FTPS etc., supports drivers for main operation systems (USB driver
for Windows, Linux and Android etc.) and software function, AT commands are compatible
withSIM7500/SIM7600 series modules.
