Though, as the earlier person said with his link to the schematic of the USB key, I would highly reccomend for home hobbiests to stay away from QFN packages, they are hard to solder with a soldering iron, and most people do not have a hot air station, and a Paint stripper would be very hard to use for a first timer to solder the IC.
Here is an example of soldering a QFN package with hot air.
I hope someone can port this code to a PIC, as they are much easier to use since they are DIP, such as the pic18f4520 or the 18f4550. I do not think they can though because of the PID changes on the fly.
Too bad my thread got merged with this one, I was hoping that it would be a tad more orginized than this
I also want to make my own, but am very reluctant to spend money on shipping and that SMD adapter
Just struck me though, you can use a old board that has the same pitch and amount of pins if you can luckly find one. Cut out the board that has the pads for the IC, desolder previous IC, and solder on the new ic, and then solder on some high gauge wire to the pads and plug it into a bread board if you REALLY want to save money
Oh well, I hope I helped some people out that wanted to make their own PSGroove
Best of luck everyone!
