This chapter introduces the description, features and application areas of Base HAT.

You can insert 3G/4G & LTE mini PCIe modules and this Base HAT becomes a bridge between Raspberry Pi and modem. This cellular HAT provides simplified data connection for remote IoT projects, on the field, across the globe, everywhere. Start using a high-speed LTE connection with low power consumption in a slim form factor with all necessary software for Raspberry Pi. You will need to get a miniPCIe module to make it works.


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 high-bandwidth cellular connectivity on your remote devices. From low-power consumption LTE-M to ultra-high-speed LTE-Advanced mini PCIe cards supported by this HAT. Both UART and USB communication with modules is available on the HAT.

Remote management of your devices on the field, secure connection over the mobile network, reliable coverage across the globe with lots of carrier options is available with this HAT stacked on the Raspberry Pi. It can be used as an LTE modem or dongle. If you’re looking for a Raspberry Pi LTE HAT for applications like Raspberry Pi video streaming or high-speed data transferring, you are in the right place. Making a remote controllable LTE Wi-Fi Hotspot, high-speed GPS tracking, more and more use case is possible with his add-on board.


  • Plug-and-Play Setup: Easily integrate with various Pi models (A+/ B+/ Pi 2/ Pi 3/ Pi 4/ Pi 5/ Zero).

  • Ideal for Development: Suitable for PoC, prototyping, and pilot production.

  • Global IoT Connectivity: Seamlessly link Raspberry Pi to Mini PCIe modem modules.

  • Fast LTE Data: High-speed connectivity between modem with optimized power efficiency.

  • Unlocked SIM Compatibility: Exposed micro SIM card slot for flexible data options.

  • It can be used standalone with a 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. A specially designed 90-degree right-angle micro USB cable is included in to package.

  • Efficient and low quiescent current power circuit can hold up to 3Amps.

  • Optional Send/Receive AT commands over Raspberry Pi UART port is available.

  • Taking the module into the Airplane Mode, resetting module or RI and DTR functions can be accessible over GPIO pins.

  • The power of the whole board electronics can be disabled for low-power consumption use cases.

  • Certified & Ready: Pre-certified with FCC, CE, RoHS for hassle-free deployment.

  • Working temperature range: -40°C ~ 80°C.
