BOTH, and anything else too!

You can add them all, and keep adding other things too. You aren't limited to just one at a time. This is the "RNA BUS" system that Curt is talking about. It means you can have as many accessories as you like and they all work via the same connections. Kind of like stacking one on top of the each other.

This.

sorry its my fault, in electronics a "bus" completely conveys the system I'm talking about and I shouldn't expect everyone to know the technical meaning. Its three wires that can be split as many times as you want, up to the number of addresses, here, like this:



That is an I2C bus, not quite the same thing (i2c is a two-wire protocol, RNA is a single wire) but you see how you can hang as many devices off of it as you want? So oled, button, sure. Hopper? maybe in the future, or a second OLED, or a THIRD OLED if you feel the need.

clear?

hhmmm, more than one OLED. Now I need to find a reason for that...

[jptheripper]

oh absolutely wow. I think i get it. Thank you for taking the time to explain.

Anything in any Rulebook against a HUD?

FINALLY drew up the OLED board.

OLED side (wasn't sure what else went there)

Beautiful! there is a ribbon cable that wraps around from the ZIF socket but I know how difficult it can be to make that look right. There is nothing on the front side so it will lay flush with whatever it is mounted on.

Fantastic. I figured that was the case. The ribbon cable is a PITA (tried for a bit to do one) so I left it off. I can put it on if you want me to but I'm not sure if it'll look nice.

I did a quick render of the OLED board into an 05 frame, looks nice and would fit very well.

Button Board:

the pushbuttons are quite a bit smaller and lower profile than you show there (they are also surface mount)

So I am delving into constructing a reflow ez-bake oven. ( I know I kept calling it a wave-soldering device, I spaced)

Ok. They didn't really look right to me, but when I searched the part number that's what showed up. I'll update it tomorrow.
