Serious consideration was given to deleting the FT245RQ but honestly the numbers don’t add up, just spend a couple of dollars and do it right. The ultraDMX Micro has 3 chips and 2 are QFN32’s to keep size minimal. The only 2 chip solutions are usb open FT232R based devices and non usb pro compatible using a USB micro. You still can’t make something truly usb pro compatible without using an FTDI FT245R device (okay so you could but it would violate FTDI IP and driver license terms since you’d be cloning their hardware functionality) so it’s still 3 chips. Perhaps when LED PAR cans cost $10 it might be worth the effort but you get what you pay for and cheap LED stuff is currently 4x that price and probably headed for a landfill near you after a short while…. IMO there’s little point being much cheaper than the current batch of interfaces.
Having debated this one several times over many years I concluded that an interface cost of $40-$100 is now insignificant compared to the cost of your lighting rig and interconnection leads.
