10GTEK Mini PCIe 2.5G Ethernet Network Card, 30-cm Cable Length, Single Port RJ45, Mini Pice Interface, not for M.2

Works well once wired correctly. Comes with no connection details, just pictures on the product page. Pay close attention to colour positions. It took me 3 goes to get it correct.

Works as advertised:) and comes with drivers

I bought the mini-PCIe card with LEDs. It came as a complete kit in a tidy box with screws, back plates, and even a screwdriver. The quality looks good, and it was well packaged. The only issue is that the 10Gtek web site has no manuals. While there are white triangles showing pin 1, they're tiny, and they only show pin 1 for the data cable, not the LED cable. Luckily, the four pin LED cable had the same orientation, although you need to be aware that pin 1 of the data cable is right next to the LED cable pins on the ethernet card (there's a gap between the two making it clearer on the RJ45 board). Other than that, I got the impression that this was well made and have had no issues using it.
