Testing

Insert the SIM card and earphone to the SIM7600X board, if you want to test the TF card slot, you can also insert a TF card to the card slot.
Connect the USB interface of SIM7600X board to PC.

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:

【Note】If you want to let the module power on automatically after booting, you can just connect PWR pin to GND and connect P7 pin to GND.
