OLED expansion is not stackable
-
Hey Guys,
I got my Omega, dock and OLED expansion a couple of days ago, and I'm impressed with this wonderful creature!!! however, I expected that OLED expansion would be stackable similar to some photos on the website but mine is not, is there any other way to use the OLED expansion and GPIOs at the same time without soldering? (OLED expansion with some male-to-female jumper wires attached to that) , Thanks.

Hi @Mohammadamin-Haghighatbin, we designed OLED to be non-stackable, whereas all other expansions are. This is because we think the OLED will always be on the very top (otherwise you wouldn't be able to see it). And having the huge female header on the OLED blocks the screen from certain angles.
I hope this answers your question!

@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.
