Many of our customers ask if we can design board with two or three Gigabit Ethernet interfaces. The Allwinner chips we use for OLinuXino are general purpose not communication chips so they usually have single Ethernet. The Sitara SOC we use AM335X advertise to have more than one Ethernet interface but it’s marketing as these are virtual interface i.e. share transfer speed.
USB-Gigabit allow you to add 10/100/1000Mbit interface to any of your computers which has USB host. It supports USB 1.1, USB 2.0 and USB 3.0 interfaces and speed depend on your USB port speed.
Our tests with A20 OLinuXino boards with USB 2.0 host interface show 319Mbit of Upload and 295Mbit of Download speed i.e. x3 times more than our other USB-Ethernet-AX88772B interface.

Thanks you.
Both for providing an OSHW Gigabit adapter, and for pointing explicitly at the confusing marketing speak regarding alternative (non-)options.

Which chipset is used here, to select the right drivers for macOS or iOS and our Raspberry PI. Or can you point me to the drivers.

The schematic on Github says it is RTL8153VCCG.
BTW, Olimex, you forgot to add alink to the repo in the product page:

Thanks for your note! I’m pretty sure I did, but obviously forgot to save page changes 🙂 now fixed

+1 for dual port Olinuxino with proper case 🙂
Why not make something like this:

So we don’t have to wear additional USB gadget with the Olinuxino board. Isn’t it possible to embed this device on the board? That would make it a good industrial VPN router.

Awesome. Hi olimex.. do you have any benchmark throughput numbers on usb 3.0 ports?
Feb 12, 2020 @ 14:26:24
The. RTL8153 is capable of ~940 MBits/sek in both directions.

Hi, just got my USB-Gigabit, and when I use it I get:
usb 2-3: new SuperSpeed Gen 1 USB device number 5 using xhci_hcd
usb 2-3: reset SuperSpeed Gen 1 USB device number 5 using xhci_hcd
r8152 2-3:1.0 (unnamed net_device) (uninitialized): Invalid ether addr 00:00:00:00:00:00
r8152 2-3:1.0 (unnamed net_device) (uninitialized): Random ether addr 42:c7:a4:e6:f0:f6
so not a fixed MAC address. Is it supposed to be this way?
Cheers,

It seems, there is no EEPROM on my board, where I guess the MAC would be stored?
Cheers,
