Feurig designed an Arduino USB programmer around the At90USB162 chip –

There were a few lessons that I learned at the Arduino Cult induction workshop that I put together this month. One of which was that I needed to simplify my programmer design on the cable end and not wait until I had a full blown product. Revisiting the original I first revised the ftdi boards to use a pinout compatible with the programming end of the rbba[really-barebones-arduino -ed.]. Then I went back to the AT90USB162 based programmer modified the schematic to reduce the parts count.

Nice work – If you’ve ever tried to use those open pads on the end of the standard USB Mini (TX isn’t connected), you’ll appreciate a programmer redesign – Benito#7 The next big thing.
