I'm working on a project that monitors the speed of internet. The board I require is very, very simple. All I need is Gigabit Ethernet to monitor the speed and then publish it to the web. It doesn't even need memory, just enough to run the program and the os. I've been looking around and I can't find a board that comes with gigabit ethernet and that is cheap (~$10 or less). If there was a board that was capable of running gigabit ethernet then I could add a jack, as long as the price didn't go too high. I've looked at the raspberry pi zero, but then I add in the cost of the adapter, the sd card, etc. I will use the Pi Zero if there is no other option but I figured I would ask before.
Thanks!
