Assembly

This page describes how the Main and Carrier boards mate.

Assembly sequence

  1. Preparation (with the system powered off): make sure the Main's mini-PCIe connector and the carrier slot are clean and undamaged.
  2. Insertion: present the Main to the mini-PCIe slot at ~45°, aligning the polarisation key, and push it fully in.
  3. Latching: lower the board until the side clips snap into place.
  4. Fastening: screw the standoff/screws into the mounting holes.
  5. Antenna: connect the active GNSS antenna to the RF connector on the Main board (not on the carrier).
  6. Host: connect the USB-C cable to the carrier.

Warning

Do not insert/remove the Main while the system is powered: always disconnect USB before working on the coupling.

Checks after assembly

  • At power-on the power LED (green) lights up steadily.
  • When the host is connected via USB-C, the device is recognised.
  • With the antenna under open sky, acquisition starts within a few seconds (fix LED blinking → steady).
