Product Description

This is the newest version of our Raspberry Pi 3G – 4G / LTE Base Shield, the smallest, most easy-to-use, and most versatile Cellular Communication Shield we ever designed.

  • There is a clip-in Mini PCIe socket for your communication need.
  • With the 4G/LTE Module(EC25) you can reach 150Mbps downlink and 50Mbps uplink data rates and the 3G Module(Quectel UC20) delivers the maximum data rate of 14.4Mbps downlink and 5.76Mbps uplink, and – The modules have built-in GPS/GLONASS for your location-based applications.(Extra GPS/GNSS antenna is required)
  • The modules of different regions&frequencies are in stock. You’ll need the get the compatible module with your region or carrier. Let us help you to while choosing the right module if you need: [email protected]
  • The Micro Sim Card socket can easily reachable on the upside of the shield.
  • The shield is fully compatible with the single 40-pin expansion header of Raspberry Pi. With the 55 x 65mm dimensions, the shield is a perfect fit for Raspberry Pi.
  • The shield can be used standalone with your PC/Laptop over Micro USB, without stacking with Raspberry Pi.
  • You will get the special designed Micro USB cable- as you see on pictures-  as a gift.
  • SMS send/receive
  • Power and Signal LED
  • Micro USB Connector
  • External 5V connection
  • 3 different ways to supply 5V input: R.Pi pins, USB connector and external 5V input. All these inputs are connected parallelly with each other, e.g. when 5V energy is supplied to the Base Shield connected to the Raspberry Pi, then Raspberry Pi also gains the power. So, you can use the different batteries or power sources as you need.
  • Options for Long header, short header and without header
  • Optional Send/Receive commands over R.Pi UART port (Attach 0 ohm resistor to the UART Resistors section below the shield or short it using a wire.)
  • Taking the module to Airplane Mode, resetting module, RI and DTR functions control can be done over R.Pi pins.
  • Possibilities to connect with Windows or Linux OS computer/laptop via USB like 3G 4G/LTE USB Dongle Modem. Drivers can be downloaded from Quectel official website.

    For 3G:  http://www.quectel.com/product/uc20.htm

 

The Differences Between Old Version: 

  • %25 smaller
  • No more need to screwing modules to shield. Thanks to the clip-in Mini PCIe socket, it’s more fun to mount the module on the shield.
  • The Sim Card Socket is a Micro Sim Card Socket now, and it’s on the upside of the shield.
  • The new power regulation circuit is more efficient and optimized so it’s cooler than old version while working.
  • No more bulky DC-Barrel Jack! The power input of the shield is 5V and can be obtained via Micro USB or power pins.

 

What is the header option? It’s so basic:

 

header_options-2

 

N.B :
Since 3G and 4G provides high speed internet, the communication is done over USB with Raspberry Pi. It can be connected with the USB cable provided with the Base Shield. UART can be also used for the internet connection but the speed will be very slow.

Functions to be controlled over Raspberry Pi Pins

Pinouts can be seen from the pin layout.

RI: Ring indicator pin. The indication for receiving call or SMS can be calibrated to HIGH or LOW using the AT commands. For details please check Quectel EC25 and UC20 AT Commands Manual.
DTR: When the module is in sleep mode, DTR pin allows to wake the module up by pulling it to LOW.
W_DISABLE: The module is taken to Airplane Mode i.e. the internet is disconnected.
PERST: This is used to the hardware reset.

 

Significance of LEDs:
PWR LED: Red LED. If the LED is ON, module is powered up.
SGNL LED: Blue LED. It indicates the status of the connection. If there is no connection the led will remain OFF. When the connection is established and data is being transmitted/received the LED will blink with specific intervals.

    :

    what bands are supported by this stuff ?

    • :

      Hello Yadi,

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

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

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

    • :

      Hi, Please choose Ec25-E (Europe).

  4. 3 out of 5

    :

    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.

    • :

      We will ask to Quectel and will turn to you

      • :

        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?

    Dear Sir,
    i am living in Hong Kong. What kind of EC25 module should I use to make it work. And if I want to use this product in Canada. Do I need to buy another EC25 module? Please advise. Thank you!

    • :

      Hello Terry,

      You can use EC25-E in Hong Kong. If you want to use in Canada with EC25-E, it can work with Rogers,Telus, Sask Tel GSM Opetators.

      Thanks

    :

    very excited to try this with tmobile. Will this board work with the new raspberry pi 3B+? And if so will it use the built in wifi of the raspberry pi for sharing the connection? I am trying to make a portable hotspot.

    :

    Is there a data sheet available with the complete list of LTE Bands that is supported.

  12. 3 out of 5

    :

    Do you have any API support for making and dropping calls from the module ?

    • :

      Our new shields (V2) don’t have Audio layer for making calls.

    I have an EC20, the base shield works with the EC20?

    • :

      Yes, You can use it 😉

    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

    • :

      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.

    :

    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.

    Greetings

    • :

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

    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. 4 out of 5

    :

    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

    • :

      Unfortunately, You have to reconfigure GPS on reboot.

  18. 5 out of 5

    :

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

    • :

      You can use an active or passive antenna.
