Wiring 128x64 OLEDs
Solder Header
Before you start wiring, a strip of header must be soldered onto the OLED. It is not possible to
"press-fit" the header, it must be attached!
Start by placing an 8-pin piece of header
with the long ends down into a
breadboard for stability
Place the OLED on top so all the short
ends of the header stick thru the header
pads
Finish by soldering each of the 8 pins to
the 8 pads!
I2C or SPI
The nice thing about the 128x64 OLEDs is that they can be used with I2C (+ a reset line) or SPI.
SPI is generally faster than I2C but uses more pins. It's also easier for some microcontrollers to
use SPI. Anyways, you can use either one with this display
Using with I2C
