Connect oled expansion and omega 2+ only

[Ericke Rafael Gallardo]

Is it possible to connect the Oled expansion directly to the Omega 2+?

I want to use the omega2 as a wearable device with an oled screen on it.

@Ericke-Rafael-Gallardo Yes.

OLED Expansion Header pinout (top view)
     +-----+ 
 GND | 1  2|
3.3V | 3  4| VDD25 / Omega2(+) GPIO11 
     | 5  6|
     | 7  8|
     | 9 10|
     |11 12|
     |13 14|
     |15 16|
     |17 18|
     |19 20|
     |21 22| SCL  GPIO4 Omega2(+)
     |23 24| SDA  GPIO5 Omega2(+)
     |25 26| GND
     |27 28|
 GND |29 30| 3.3V
     +-----+ 

Connect pin4 to pin3 on the OLED Expansion Header.
Connect the GND, 3.3V, SDA, SCL pins to the GND, 3.3V, SDA, SCL pins of Omega2(+) respectively.

I suppose every GND pins are common and also every 3.3V pins are common on the OLED Expansion board.
I do not have any genuine Onion OLED Expansion please check this (eg. with an Ohmmeter) or try this and correct me if I am wrong.

@György-Farkas wow! Thankyou so much!
I just got mine. I had fun testing it. I'll try this schematic of yours. Probably I'll post an update if this works.
