  • The PWR indicator turns on after connecting
  • Long-press the PWR button for 1, the NET LED turns on and became flashing after 10s. (If the NET indicator keeps solid, please check if the SIM card is workable)
  • Check the Device Manager of PC, the several COM ports will be recognized:

  • If the COM ports are recognized with an exclamation symbol, you should install the driver manually.
  • Connect the DONGLE to Windows PC (Hereafter we use Windows 10 PC as example))
  • Open Device Manager—>Other Devices—>“SimTech, Incorporated”—>Update driver—>Browse my compute for driver software—>Choose the driver according to your OS—>Install it
  • After installation, all the devices should be recognized normally as below:

The hardware configration of the New Version

After December 23, 2020, SIM7600G-H 4G HAT began to release a new version; compared with the old version, the new version has the following changes:

SIM7600 NEW old.png
  • 1) Newly added 330uF electrolytic capacitor (Stronger voltage stabilization ability)
  • 2) Newly added PWR and Flightmode pin jumpers (Automatic power-on function can be set, and the IO port can be customized to control the switch and Flight mode)
  • 3) Add solderable pads for VCCIO.(when used with Raspberry Pi, the SIM7600X 4G HAT is soldered at 3.3V working level by default; if you need to use 5V working-level MCU, you can change it to 5V by yourself)
  • 4) Add solderable pads for the module USB. (if you don’t want to use a USB adapter cable, you can solder them to the corresponding USB solder joints at the bottom of the Raspberry Pi through some flying cables. This operation should be used with caution by non-professionals)
  • 5) The capacitance is changed from the original 10uF/6.3V to 100uF/6.3V (stronger voltage stabilization ability)
  • 6) The silkscreen naming is changed from "WPI naming" to "BCM naming"
  • 7) Fine-tuning the layout
  • 8) Add new solder joints for module Boot to burn the firmware forcibly. Short-circuit the two pads can enter the forced firmware burning mode. (Only used when the firmware cannot be burned normally)

Description of turning on/off the HAT for New Version

  • In the new version, PWR and 3V3 are short-circuited by default, so the HAT turned on automatically after connecting to the power supply.
  • If you need to use the PWRKEY button to turn on/off the HAT, please remove the jumper cap between PWR and 3V3:
  • If you want to use the Raspberry Pi to turn on/off, please set the jumper cap between PWR and D6:

Flight mode description of the New Version

  • The new version of the HAT doesn't turn on the Flight mode by default:
  • If you need to control the Flight mode through the Raspberry Pi pins, set the jumper cap between Flight and D4:

FAQ

Question:
NET light does not flicker after startup of SIM7600X, what should I do if the network is abnormal?
Answer:
This situation may not be successfully connected to the network, you can follow the steps below:

Firstly, check the hardware connection, check whether the antenna is properly connected, and check whether the +SIM card can be used to make normal calls and surf the Internet in mobile phones and other devices: After checking the hardware connection, the software can use these instructions:

  • Check whether the SIM card is in good contact: AT+CPIN?
