Before we jump into the tutorial, let us check all the items required for this is available with us and prepare our hardware.

Hardware Prerequisites

Most of these are the parts you will receive when you order the Cellular Modem Kit with Quectel modules.
The goes as follows:

Raspberry Pi (Model 4 or 5 are recommended)
Sixfab 3G/4G & LTE Base HAT
Quectel EC25/EG25 mini PCIe Module or Quectel UC20-G Mini PCle 3G Module
LTE Full Band PCB Antenna
LTE – GNSS Dual u.FL Antenna
40 pin header
Right Angle Micro USB Cable
Sixfab SIM or other available SIM

🟢 Make sure your Sixfab SIM is registered and activated on the Sixfab Connect.

📖 Note

Optionally, you can use Triple Port u.FL Antenna as an antenna or any other combination of LTE and GNSS antennas.

Hardware Setup

1. Attach the Quectel EC25/EG25 mini PCIe module to the HAT.

2. Attach the antenna to the mini PCIe module.

Make sure the right antenna is connected to the right port. Attach LTE full band PCB antenna/LTE connector of the LTE-GNSS dual antenna to the main Antenna interface/diversity antenna interface & GPS Antenna portion goes to the GNSS antenna interface.

3. Attach 40 pin header to the Base HAT that comes with the HAT and insert the Sixfab Connect SIM to Base HAT.

4. Now attach the HAT to the Raspberry Pi.

5. Finally connect the micro-USB cable to the HAT and Raspberry Pi.

Checking Driver

Then open up a terminal and run the commands below. Expected outputs are as follow:

pi@raspberrypi:~ $ lsusb Bus 001 Device 009: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
