It's called the "MiSTer Input Latency Tester", a homebrew project you can build yourself with an Arduino Pro Micro and a little soldering.

The project uses work from Jorge, Lemonici and Porkchop Express from MiSTerAddons.

If you have ever used the "MiSTer Input Latency" Google sheet, this is the device which produces those results: rpubs.com/misteraddons/inputlatency
