} Is the base shield works with any other 3g/4g/lte modules except quectel? (huawei, telit, sierra etc.)
Generally, different modules’ USB, power supply, status led and SIM Card pins match with Quectel’s Pinout but it does not mean full compatibility, some features may not work.
} What is the difference long header option to the others? Why ı should choose long header option?
Long Header: If you plan to attach another Raspberry Pi HAT or add-on board on top of the Base Shield, you will definately need these variation. Also, using GPIOs with jumper cables is possible with these male headers.
Short Header: Are you going to use Base Shield only, will not add another Raspberryi Pi HAT or shield on top of it? Or you’ve already attached a board with long header on Raspberry Pi and you’re planning to plug the Base Shield on top? This header option is suitable for you.
Without Header: If just the plugging Base Shield via micro USB cable to Raspberry Pi is enough for you, or you’ve already attached a bulky shield on Pi, doesn’t need UART communication, this slim, headerless shield works greatly. For knowing what you missing without headers, take a look at the Pinout Diagram of the shield, these pins will be unconnected.
} Without header options can work with only USB connection?
Yes. Because Raspberry Pi GPIO pins are not connected to shield on without header option.
} Does the shield work with all version of the Raspberry Pi ? Raspberry Pi 3 Model B+ or Raspberry PI Zero W?
The shield is compatible with RPi versions below:
- Raspberry Pi 3
- Raspberry Pi 2
- Raspberry Pi B+
- Raspberry Pi A+
- Raspberry Pi Zero
} Can I use with other USB Cable?
We don’t recommend usage of long and low-quality micro USB cables between Base Shield and Raspberry Pi. It causes data and power loss. Thus, the cable included the package works greatly.
} Can I use with UART connection?
Yes. If you insert one of Quectel Mini PCIe module, the UART pins will be available to use, with 3.3V power domain, directly connected the UART port of Raspberry Pi. But the maximum data rate will be lower than USB. It’ll be around 900 Kbit/s Downlink and Uplink (UART)
