Would the U-HID nano be enough to do a pole position cockpit? 360 wheel, 2 analog pedals, and 3 "buttons".
I don't think, but you could check with Andy about some of these workarounds:
The analogue inputs sense voltage, so if you used an external 5v power source, you'd only need one pin per pedal.
That looks possible on pg 11 of the manual (the nano has the same functionality, just fewer pins):
http://www.u-hid.com/u-config/u-hid%20Manual.pdf3 pins + ground for buttons leaves only 2 pins for the optical encoder.
This is where I think we run out of room.
If the optical encoder can use power from an external source, that would just get you there.
But judging from the examples, I'm guessing this isn't possible.
I'm sure Andy could answer it in a heartbeat if you emailed him.
