Yes, need to be careful of knock off's for sure, been bitten a few times. I've always want to combine all my IR remotes into one, never got around to it aside from reading about it, a project for another day.
We buy single FTDI and 4 port FTDI USB chips for our USB to RS485 cards. Most of the arduino projects are for work for in-house testing of finished products. Next slow horse project is for personal use , we buy 60 Grandstream VoIP phones every year, pull out the card and embed it into our suite/Panic controllers to interface to old analog audio for suites and remote panic stations. Been tossing the GS phone cases out until recently, thought I could use the LCD and keypad for some of my personal projects, got the graphics LCD working using a PIC24, going to port it over to arduino soon. I cut off the handset cradle. If you want a few, let me know, I'm happy to mail them to you from work.
