No problemo. I dorked-up the 1st one with the wrong 64-pin TQFP package type anyhow, so I had to change it. The PIC32 we're using is 10x10x1 with 0.5 lead pitch. That just made it even harder to route, but did give up a teeny bit more realestate.
It needs to fit on a breadboard anyhow since it's not dev-board size, so I spent a few hours changing it around. A 2x8 female header for the analog pins should make it nicer than the 1x16.
And I went by the datasheet VS the Sparkfun schematic for the VUSB connection (pin #35) to the cap. It's not crystal-clear what they're doing with this pin. It shows ---> with 3.3V just below it. Not sure if they didn't connect this pin or if they ran it to the other 3.3V connections with --->3.3V?
It could be a LOT smaller with < 0805 components, but it wouldn't be anything I would even consider assembling by hand unless it was just 1 or 2 units. And the price per board would definitely go up, so I'm leaving it at this size.
I'm going to get in touch with Rich on a clone connector. If I have room, I'll try to squeeze that in too. Then you could connect 2 boards & clone them, but that's a big maybe. If it turns out to be a hot item, I'll make it really small, and probably even ad the wireless, but I'll have someone else assemble them. I just want 1 to mess with to see how it works with the BASIC OS for starters.
