Does it what it says it would
For Quad Serial Breakout
Turned up today. Soldered some headers on in around 5 minutes. Plugged it in - was recognised as 4 serial ports straigh away.
Connected to 4 instrument ports and happily showing me diagnostic information. Takes up a hell of a lot less room and cabling than the old setup of four separate adapters, and they have also been repurposed for other projects now.
