Hi all,

I am looking to connect 3-ply conductive thread to the GND, Vin, SCK and Data pins (I2C mode) of this 128 x 128 px grayscale OLED by Adafruit:
Grayscale OLED

Board: Teensy 4.0
OLED: SSD1327 Grayscale

The constraint is that I need this whole thing to go into a wearable (hoodie), so it should be as slim and low-profile as possible.

I am looking to connect as much as 4 feet of the thread, and I understand that there is a certain resistance per foot for the thread of about 10-16 Ohms that could be limiting the current that the OLED requires.

I have already tried what I'm describing (connecting the thread to the OLED), and the results were unsatisfactory: OLED power light turns on, SSD1327_test.ino successfully uploads and Serial confirms that the display has initialized. Sadly the display shows a blank screen, but when I use jumper wires it lights up and performs the test.

I'm thinking I could find a way to boost the current travelling through the wires,

OR

Use a different material than the thread,

OR...

You tell me!

Any guidance, questions, concerns, comments, advice, expertise, help greatly appreciated.

Thanks!

If the wires run inside the hoodie what's the problem with using 'ordinary' wire which just happens to work?
