I have a pole position control panel so I will be using optical steering, 1 shifter button and analog accelerator.
- 4 pins for optical steering (5v, ground, data1, data2)
- 1 more for analog accelerator (should be able to share the 5v and ground)
- 3 more for the shifter, Coin, and Start buttons (should be able to share the ground)
- 1 more for a dedicated Esc button (should be able to share the ground)
or none if you set it up as a shifted function (Coin + Start)
That adds up to 8 or 9 pins which would fit on a U-HID Nano.
Assuming that the games on your list work with a one-switch shifter
and that you can share one ground, you should be good to go.
There is one possible limitation.
+5 Volts out (max 30 ma)
If the optos and pot draw more than 30mA, you should be able assign two pins to 5v and either:
1. Use the shifted function for ESC
2. Use diodes + shifted function for dedicated ESC button
3. Use "reverse wiring" + shifted function for dedicated ESC button (like KADE Extended Mode Up+Down "impossible keypresses" in
this wiring diagram)
