<br />
== Technical overview ==<br />
* The module features a 40-pin GPIO expansion header for connecting to host boards such as Jetson Nano or Arduino.<br />
* It supports dial-up, calls, SMS, email, TCP, UDP, DTMF, HTTP, FTP, and other network protocols.<br />
* GNSS capabilities include GPS, BeiDou, Glonass, and LBS base station positioning.<br />
* Baud rate range: 300 bps to 4 Mbps; default 115200 bps.<br />
* The board includes a SIM card slot supporting 1.8 V and 3 V SIM cards.<br />
* An onboard TF card slot allows storing files and messages.<br />
* An onboard audio jack and audio decoder chip enable telephone calls.<br />
* Two LED indicators monitor the module's working status.<br />
* Operating voltage can be set to 3.3 V or 5 V via jumper.<br />
* Shipped with online resources and demos for Raspberry Pi, Jetson Nano, Arduino, and STM32.<br />

== Notes and version constraints ==<br />
* The exact band coverage of the SA variant must be confirmed against local network data before purchase.<br />
* When using with a 5 V MCU, the VCCIO solder pad must be manually changed to 5 V; this requires soldering work.<br />
* Forced firmware flashing is done by short-circuiting two pads; use only when normal flashing fails.<br />
* The new version powers on automatically by default (PWR shorted to 3V3); remove the jumper for manual power control.<br />
* Flight mode jumper is not enabled by default; to control via Raspberry Pi pins, set the jumper between Flight and D4.<br />
* MMS is not supported by the SIM7600x series.<br />
* The reset pin was not broken out because it only resets a small subset of functions (similar to AT+CRESET).<br />
