5. Setup Guide

5.1 Hardware Installation

1. Install 5G Module: Carefully insert your compatible M.2 5G module into the M.2 B KEY slot on the HAT. Secure it with the provided screw.
2. Attach Antennas: Connect the four cellular antennas to the SMA connectors on the HAT. Connect the GNSS antenna to its dedicated connector. Ensure all connections are finger-tight.
3. Insert SIM Card: Open the SIM card slot cover and insert your activated Nano-SIM card(s). The HAT supports two SIM cards for dual standby.
4. Connect to Host Board:
   • For Raspberry Pi: Align the 40-pin GPIO header of the HAT with the Raspberry Pi's GPIO pins and gently press down to connect. Ensure proper alignment to avoid damage.
   • For PC/Jetson Nano: Use the provided USB 3.0 cable to connect the HAT's USB 3.1 port to your host device.
   • For CM4-IO Base: Use the purpose-made USB adapter for connection.
5. Power Connection:
   • If using with Raspberry Pi, the HAT can draw power from the Pi's GPIO.
   • For standalone operation or if additional power is required, connect the 5V 3A Type-C power adapter to the HAT's USB-C port. Ensure the power switch on the HAT is set to the appropriate source (USB or external Type-C).
