== Summary ==
Technical guide for the Waveshare SIM7600E LTE Cat-1 HAT: specifications, power on/off, flight mode, AT commands, and debugging via UART/USB.

* [https://shop.jw-tech.eu/p/WSAL17954 WSAL17954 – SIM7600E LTE Cat-1 HAT for Raspberry Pi, 3G / 2G / GNSS as well, for Southeast Asia, West Asia, Europe, Africa]

== Technical overview ==
* Supports LTE Cat-1 with up to 10 Mbps download and 5 Mbps upload.
* Also provides 3G (HSPA+) and 2G (GSM/GPRS/EDGE) plus GNSS positioning (GPS/BeiDou/GLONASS/GALILEO/QZSS).
* Features a 40-pin GPIO expansion header for connecting host boards such as Arduino or Jetson Nano.
* Onboard CP2102 USB-to-UART converter enables serial debugging and AT command testing.
* SIM card slot supports 1.8 V and 3 V SIM cards; optional TF card slot for storing files and SMS data.
* Connections include USB, UART, audio out (for calls), LTE main and diversity antenna connectors, and a GNSS antenna connector.
* Operating voltage is selectable via jumper between 3.3 V and 5 V; default with Raspberry Pi is 3.3 V.
* Newer versions add a PWRKEY button, flight-mode jumper, and forced firmware flash pads.
* LED indicators show network status; the NET LED blinks once per second during normal operation.
* Ships with online resources and sample demos for Raspberry Pi, Jetson Nano, Arduino, and STM32.

AT+CGPSINFOCFG=10,31
AT+CGPSAUTO=1
AT+CRESET
</syntaxhighlight>

== Notes and version constraints ==
* The SIM7600x series does not support MMS.
* The reset pin was not broken out because it only resets a subset of functions (equivalent to AT+CRESET).
* Forced firmware flashing requires shorting two solder pads – use only when normal flashing fails.
* Changing the IO level from 3.3 V to 5 V requires soldering the corresponding pads; not recommended for non-professionals.
* Flight mode is disabled by default on newer versions; enable it by setting the jumper between Flight and D4.
* Automatic power-on means the device cannot be manually powered off; reduce power consumption by turning off RF or entering flight mode.
* If the GPS NMEA port outputs no data, restart the module after sending the listed AT commands.
