Header Options

Alt text

  1. Long Header: If you plan to attach another Raspberry Pi HAT or add-on board on top of the Base Shield, you will definitely need this variation. Also, using GPIOs with jumper cables is possible with these male headers.
  2. Short Header: Are you going to use Base Shield only, will not add another Raspberry Pi HAT or shield on top of it? Or you’ve already attached a board with a long header on Raspberry Pi and you’re planning to plug the Base Shield on top? This header option is suitable for you.
  3. 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.

 

Technical Details

Connection Types

USB: Most of Mini PCIe modules have USB driver for Android, Linux, and Windows operating systems. The Base Shield that loaded with a module like Quectel EC25 LTE, can be attached to a minicomputer(especially Raspberry Pi), mobile phone or laptop with USB then works as a 3G/4G USB Dongle Modem. Drivers for modules, please visit the module product pages.

UART: If you insert one of the Quectel Mini PCIe modules, 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)

Important Note(*): Please check the following Quectel Mini PCIe pinout(EC20,EC21,EC25,UC20) diagram and the Base Shield connected pin table for full compatibility.  The other Mini PCIe modules from different vendors can be used with the Base shield. Generally, these modules’ USB, power supply, status led and SIM Card pins match with Base Shield Pinout, they can be used via USB connection without struggling but it does not mean full compatibility, some features may not work. The AT Command Interface cannot be used without UART connection. Please, consider USB connection needs special drivers for each operating system.

    Martin G. –

    Hi, we have this Ec25-E (Europe) card in Germany but it just work with G3. Did you have some hints to fix this bug and get LTE Speed? Our sim Card contract is working with LTE we tested it with a LTE stick.

    • Metin –

      We will ask to Quectel and will turn to you

      • Mahmut –

        On the EC25 module, 4G is open by default and connection priority is available. However, if there is no 4G signal in the area where it operates, it will try to connect via 3G. We can force the test module to connect to 4G Access technology. Could you try the following command for this and try connecting to the same region? Then AT + COPS? Could you send me the output of the command?
        So, the command is ‘AT+QCFG=”nwscanmode”,3’ to force the module search the network only LTE. Please see the following example.
        AT+COPS?
        +COPS: 0,0,”TR TURKCELL”,6 //Access technology is UTRAN W/HSDPA and HSUPA
        OK
        AT+QCFG=”nwscanmode”
        +QCFG: “nwscanmode”,0
        OK
        AT+QCFG=”nwscanmode”,3 //force the module to connect only LTE network
        OK
        AT+COPS?

    Hello,

    is the shield compatible with Quectel EP06 ? EP06 support carrier aggregation (for best bandwidth) and some new lte bands.

    https://www.quectel.com/UploadImage/Downlad/Quectel_EC25_Mini_PCIe_Hardware_Design_V1.1.pdf
    https://www.quectel.com/UploadImage/Downlad/Quectel_EP06_Hardware_Design_V1.0.pdf

    It seems the difference is the following mini PCIE pins. They introduced USB3.0.

    23 PERn0 UART_CTS DI UART clear to send Connect to DTE’s RTS -> 23 PERn0 USB3.0_TX- DO USB 3.0 transmit data (-)
    25 PERp0 UART_RTS DO UART request to send Connect to DTE’s CTS -> 25 PERp0 USB3.0_TX+ DO USB 3.0 transmit data (+)
    31 PETn0 DTR DI Sleep mode control -> 31 PETn0 USB3.0_RX- DI USB 3.0 receive data (-)
    33 PETp0 RESERVED Reserved -> 33 PETp0 USB3.0_RX+ DI USB 3.0 receive data (+)

    • onur –

      Hi Louis,

      In our shield, RTS and CTS pins are not connected. Reserved pin is in the idled. Only the DTR pin connected to the RPI pin. So EP06 USB3.0 RX pin connected to the RPI pin. So maybe It can work. But you can use USB 2.0 function, not USB 3.0. We didn’t try it before. So we cannot guarantee.

      Quectel EC25-AU is recommended for your location. This module supports B1/B2/B3/B4/B5/B7/B8/B28 Bands. Confirm it with your network provider too.

    Hi, I live in Panama. Here we only have LTE cellular network. I want to buy a module to use it in my Raspberry PI 3 B+ and be able to connect to internet using that cellular network with a sim card.
    The sixfab module can do that?
    Thanks

    Q What kind of certification this module has? answer now
    Answered by the admin

    This is a development device which is actually a bridge between Mini PCIe 3G/4G/LTE modules and Raspberry Pi. The module that is being used with the shield is certified. So it doesn't need any certification. 

    If someone is making it an end product then you will need to get certification for the whole setup.
