OLED expansion is not stackable
-
@Boken-Lin Thanks for your quick response,true,that makes sense...any suggestions on how we can use GPIOs and OLED at the same time without soldering?Thanks again
-
@Mohammadamin-Haghighatbin You can try to insert a thin wire into the pins on the GPIO header before putting on the OLED expansion.
-
@Mohammadamin-Haghighatbin Another possibility would be to get yourself a Proto Expansion (https://store.onion.io/collections/onion-omega-expansions/products/proto-expansion) though I note from the shipping schedule that these won't be shipping until January 2016
@Boken-Lin Perhaps there is a case for an additional Expansion board that contains connectors that allow external wiring to be easily attached to the GPIO pins

Guys, I greatly appreciate your suggestions, you're both life savers... I just ordered a proto-expansion with 10% discount
Thanks again...

Hello,
I like the proposed solutions but which ports does the OLED expansion use? I wasn't able to find the information.Thanks!
-
@Marc-Junyent-Martin OLED Expansion just uses power and ground, and communicates via I2C with GPIO 20 and 21.

you all should sell a 'pin-T' spacer. this will allow for other combos that leave you without pin access to simulataneously stack and insert leads too, like the onion omega + minidock.
-
@Theodore-Borromeo I did a quick search for pin-t spacer but wasn't able to find anything. Can you show us a picture? If it is what I think it is, i think it would indeed be very useful.

@Boken-Lin I just made it up, but it's something I've not seen in electronics that should exist. Essentially, if you think of the current stacking mechanism, you have the pcb board->plastic riser->pins from stackable expansion->pcb board. This leaves no room for more than one pin to be inserted into any through way on the plastic riser. What you all should have is a tee-ing mechanism. It would be an equivalent length plastic strip in an L shape, with the bottom of the L being pins such that you have a "T". You could then plug in two pins into one "hole" on the original board

@Theodore-Borromeo I see. Something like this would be very useful. I'll keep an eye open for something that might be able to help with this.
