Raspberry Pi 3G/4G & LTE Base HAT

The Sixfab 3G/4G& LTE Base HAT grants your Raspberry Pi or 40-pin Pi compatible single-board-computer a super-simple interface bridge between mini PCIe cellular modems. With the modems you insert into Base HAT, your Raspberry Pi based projects will access data networks all around the world. This Base HAT enables narrow-bandwidth to high-bandwidth cellular connectivity on your remote devices i.e from low-power consumption LTE-M to ultra-high-speed LTE-Advanced mini PCIe modules are supported. Both UART and USB communication with modules is available on the HAT.


  • Fully compatible with Raspberry Pi models that have the 40-pin GPIO header (4, 3, 2, A+). Raspberry Pi Zero may lack performance.
  • Easy-to-use, simple setup.
  • Clip-in Mini PCIe socket is compatible with worldwide LTE, UMTS/HSPA+ and GSM/GPRS/EDGE coverage with regional or global modules which work with different frequencies & carriers.
  • Micro SIM Card socket can easily reachable on the upside of the HAT.
  • It can be used standalone with PC/Laptop over micro USB, without stacking with Raspberry Pi.
  • The HAT can be powered from an external 5V source by exposed power pins, directly from Raspberry Pi 5V GPIO headers, via micro USB, or optional JST connector on the bottom of the board.
  • Efficient and low quiescent current power circuits can hold up to 3Amps.
  • Optional Send/Receive AT commands over Raspberry Pi UART or USB port is available
  • Taking the module into the Airplane mode, resetting module functions can be accessible over GPIO pins.
  • The power of the whole board electronics can be disabled for low-power consumption use cases.
  • The modules have built-in GNSS(GPS/GLONASS) receivers for your location-based applications.
  • Micro USB is used to connect the modem, it transmits data through the cable to the Raspberry Pi.
  • Working temperature range: -40°C ~ 80°C.

Pin Descriptions

Pin NumberBCM PinPin NameDescription
8UART_TXPCI RXThis pin functions as the serial data input to the module for UART communication. Disconnected by default.
10UART_RXPCI TXThis pin functions as the serial data output from the module for UART communication. Disconnected by default.
13GPIO27USER LEDActive HIGH, to switch on the USER LED, the pin’s state should be HIGH.
15GPIO22USER BUTTONThis pin normally pulled-down to ground. When the button is pressed, pin switches to LOW.
31GPIO6RIThis pin is Ring indicator functions as the indication for receiving call or SMS, can be calibrated to HIGH or LOW using the AT commands.
33GPIO13DTRWhen the module is in sleep mode, DTR pin allows to wake the module up by pulling it to LOW.
35GPIO19W_DISABLEThis pin is used to turn Airplane Mode on the module, by pulling it HIGH.
37GPIO26HAT_PWR_OFFPower regulator control. Normally pulled-down, when this pin drove to HIGH, Hat’s power will cut off.
Note: Quectel modules are compatible with the UART of the HAT, Telit modules are not compatible.


  • PWR LED When the module is powered up, this RED led turns on
  • SGNL LED This BLUE led indicates the status of the connection. When the connection is established and data is being transmitted/received, this led will blink at special intervals. Otherwise, if there is no connection, the led will remain off.
  • USER LED It is a programmable user-led can be controlled from the GPIO27 of Raspberry Pi for debugging or just fun.


  • User Button It is a programmable user button that is connected to GPIO22. It reads HIGH by default.

    Amazing kit! Assembled in no time (check raspberrypi official tutorial how to setup your rpi board. I have used model 3, but the tutorial is same for model 4:, run all commands as described in documentation here: using QMI interface. And voila – it works!!! My school dream came true – IOT with NO Borders!!!
    I am getting LTE 30/30 Down/Up speed – AMAZING!
    Thank you Sixfab for amazing product and clear instructions! Definitely will look for another cool stuff from you!
