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)

  1. Yadi Rudiyansah

    what bands are supported by this stuff ?

    • onur

      Hello Yadi,

      Our Shield support all bands. You just need to select the EC25 module that is appropriate for your location.

  2. Kim

    Hi. What is the power consumption for this shield with a EC25-E and 2 antennes without a PI?

  3. Magnus Eriksson

    hi i live in sweden. What kind of EC25 module should I use to make it work in Sweden and Europe

    • Metin

      Hi, Please choose Ec25-E (Europe).

  4. 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.
        +COPS: 0,0,”TR TURKCELL”,6 //Access technology is UTRAN W/HSDPA and HSUPA
        +QCFG: “nwscanmode”,0
        AT+QCFG=”nwscanmode”,3 //force the module to connect only LTE network

    It’s a very unique product but it’s very fragile, i broke the micro usb port without put pression, i just plug in the cable and the port micro usb fall down.
    I love the idea but it could be do better, please for the next protect the port with something

    • onur

      Thank you for your feedback Francesco. We changed our products, now more strong. Send us the product if you want, we can send smooth one.

  15. Karol

    Is it possible to use this shield without using any RPi GPIO pins, just only over USB (communication and power supply)? I’d like to use this shield and one another which must use GPIO pins.


    • Metin

      Yes you can use, but use have to power shield with external supply to 5V pins on pcb due to much current.

  16. Pixie

    Hi, does this work with Asus Tinker Board runnig Tinker OS? Do I have to modify the kernel or so? I want to buy this with EC25-E, but I don’t want to get into problems since I’m not a pro.

  17. Matt

    How to I pipe the gps data from this hat and have it work after power is completely cut out and reapplied? Minicom works but only as long as power stays plugged to pi. If power is pulled and reapplied it has to be reconfigured. I.e. AT+QGPS=1

    • Metin

      Unfortunately, You have to reconfigure GPS on reboot.

  18. Nick

    Do you have a recommendation for a GPS antenna? Does it need an active or passive antenna?

    • Metin

      You can use an active or passive antenna.

    • onur

      Hello Andrew,

      You can use Raspberry Pi 3G-4G/LTE Base Shield V2 with EC25-AU for Bell LTE.

  22. Louis (verified owner)


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


    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.

  23. Şahin

    Hello Sixfab team,
    Great work, congratz.
    I have a specific question. I have a R.Pi 3B+ and an additional CANBUS+MODBUS head and it has no extra head expansion on it. I need to use GPRS+GPS head from you and this head too. Can I do it? How? And since canbus+modbus are both serial ports, can R.Pi handle all these at the same time, is there any conflict of ports/buses ?

    Thank you

    • Metin


      You can use our shield via USB. If you connect via USB, you do not need to plug in the pins, only USB. And use /dev/ttyUSB0 for communication. ( Don’t forget to select the switch to USB ).

  24. anand.s

    kindly clarify the module supported in India ,EC25-E or EC25-AU for India? for Raspberry Pi 3G-4G/LTE Base Shield V2
    how to provide option of Quectel Module ( EC25-AU) while ordering.

  25. Gargoyle

    Hello looks very interesting this board!
    Is it possible to use with Quectel EC25 Mini PCle 4G/LTE Module connected to Banana Pi with pins but not USB?

    • Saeed

      Banana Pi Pins are not compatible with Raspberry Pi 3G-4G/LTE Base Shield V2. USB will be the only option left for it. Moreover UART is not the best option to connect as it will result in slow connection.

  26. Michael (verified owner)


    Can you explain to me how to use Raspberry Pi 3G-4G / LTE Base Shield V2 and Quectel EC25 Mini PCl 4G / LTE Module with raspberry?

    I do not know how to configure via the terminal.

    Are there drivers for raspberry and for windows?

  27. ANTHONY (verified owner)

    Hi, I am using EC25-AU. I tried several methods to camp on LTE network, but it seems that only 20+ MBps uplink/downlink performance. (My iPhone can get 80MBps/40MBps downlink/uplink at the same place, same telecom). Do you have any recommended antenna or something that can improve the performance? Thanks for any suggestion.

    • Saeed

      Hey, Which antenna are you using now?
      Are you using the USB cable that we sent you with the shield?

    Did you solder/short the UART resistor pads?
    Generally UART is disconnected
    To use UART, you will need to solder 0 OHM/ short the UART RESISTOR pads available under the shield https://sixfab.com/wp-content/uploads/2019/05/BaseShieldUART.jpeg

    A Yes I soldered 0 ohm resistors in place to use the UART. The strange thing is that the system works perfectly using the Quectel eval board for the EC25-E. The sixfab board does not work if it is plugged directly into the RPI but if I link the Pi and sixfab board together using a small ribbon cable then it works but sends a photograph every two minutes. I am linking the first 20 wires together ie. pins 1,3,5,7,9,2,4,6,8,10so clearly it is one of the other pins making it fail. I am tempted to remove the unused connections that are currently in place.

    This is just a Base Shield, which bridges the module to be used with the Raspberry Pi. 

    So, it will depend on the module you will be using with this Base Shield.

    By default, the UART of the Shield is disconnected. So you may use them for other purposes while the Shield is stacked.

    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.

    Yes, Raspberry Pi 3G-4G/LTE Base Shield v2 and Raspberry Pi XBee Shield v2 can be used together. 
    Communication for Base shield should be via USB(recommended). 
    XBee Shield can be connected via USB or UART.

    For compatibility, you will need to compare the pinout of the mini PCIe with the Quectel Mini PCIe pinout(EC20, EC21, EC25, UC20)  (Pinout is available in the product description).
