I do not expect many of you to know this site, but nevertheless, it deserves to be mentioned that WikiDevi has gone offline on 31-10-2019.
WikiDevi was a wiki for all kinds of networking devices from routers to switches, repeaters, IoT devices, microcomputers and even some phones. It featured rich information about the products and specific information about the components inside of devices. Various kinds of CPUs, RAM and modems in particular gave the user more information about expected performance of the device than the manufacturers webiste.
It also gave the users information what kind of alternative firmware is available for the specific device.
You can say it was something like OpenWRT's Techdata sites with a difference being that WikiDevi contained all kinds of networking devices.
Despite the lack of any reputable news sources, below is the official notice by the WikiDevi itself which has been visible for some time before the site went down.
Hopefully this counts as a source.
The official dump of the website can be found on the Wayback Machine: https://web.archive.org/web/20191031174547/https://wikidevi.com/wiki/Main_Page
For me personally, WikiDevi has been an excellent source of hardware of the networking devices as it gave me (and others) extensive information about the device.
It was especially helpful when choosing a new router to buy. The site lets you see which devices used the same chips. It provided information about the processor cores, architecture, date of manufacturing and much more.
It also gave you information about whether the Serial port for flashing alternative firmwares was soldered or if you had to solder it yourself.
I do not know the reason behind the site going down.
I'm sure there are other sites just like this one. The one example that comes to my mind is Whirlpool Hardware Database https://bc.whirlpool.net.au/bc/hardware/
If you know any others sites just like these ones, I would be grateful if you share them below.
