HatNET 2.5G

RTL8125 based 2.5 Gigabit Ethernet NIC.
Compatible with Raspberry Pi 5.


Packaging contents

- HatNET 2.5G board
- 60mm PCIe FPC cable with controlled impedance
- 4 standoffs
- 8 M2.5 screws

Assembly instructions

  1. Begin with inserting the FPC ribbon cable into your board. Use the alignment triangle to determine the proper direction, check the picture above for reference.
  2. Attach 4 metal standoffs to the board using M2.5 screws.
  3. Insert the PCIe cable into your Pi 5.
  4. Install the board underneath your Pi 5. Please note that the Ethernet port should be facing the Pi 5.
  5. Power on the board, the PWR LED should be now on. If this is not the case please update the firmware on your Pi 5 or enable PCIe (check tutorials below).


The Ethernet NIC does not require additional drivers on Raspberry Pi OS. We recommend regularly updating the firmware to benefit from constantly improving PCIe support.


HatNET 2.5G is compatible with Raspberry Pi 5 and other Single Board Computers with the 16-pin PCIe connector (for instance the Radxa 5C/5C Lite).
