It is. It's a small STM32-based uC that supports USB, and so can be
loaded with firmware to look like a USB device on a PC USB chain. The
GPIO of the uC then connects directly to the FD and tickles the signals
and reads the raw data, sending it onto the PC via USB.
Tony provided the links in the response you quoted. You can buy premade
GW PCBs, but the original design was just a small STM32 "Blue Pill" dev
board and an FD. The BluePill was like $10 or so, making this much
cheaper than KryoFLux (I believe it was designed as a rebuttal for the
high priced and "walled garden" nature of KryoFlux) or other related
projects like DiscFerret and/or discontinued solutions like CatWeazel
(which was a plug in card and harder to support on newer machines)
