    Do you have a detailed visual or video on how to connect with shield arduino to use in conjunction with it?

    When connecting to a computer using usb, the usb device is not recognized, I get the error, which drivers do I need to load? (Installed via github with Quectel windows usb drivers installed)



    1- You should connect GND/TX/RX/PWR_KEY/VDD_EXT pins to Arduino. To power-up module, PWR_KEY pin should stay HIGH 2 seconds long, then LOW. Then you can send AT commands via Serial.

    2- You should install FTDI FT230X driver. Please check this link > https://www.ftdichip.com/Products/ICs/FT230X.html

    Hi…It’s a piece of software that runs on the Arduino which sends input from the serial monitor to a device connected by SoftwareSerial, and relays any response from that device back to Serial Monitor.
