Just wanted to share my experience with people in EU that want to build the OLED display as described in the tutorial but don't fancy ordering from overseas the one that Michael recommends.
I ordered this one from Audiophonics:
Here is a very elegant 3.12 "256x64 OLED screen with superb brightness and excellent readability. It is already mounted on its PCB with a soldered connector.
It costs roughly the same, and looks quite similar. The good news is that it comes with the 16 pin connector already soldered and the pinout is the same. The bad news is that it comes set to SPI configuration, not 6800, and @Audiophonics
will not change it for you. But you can can change it yourself with a soldering iron and a bit of good luck if your soldering skills are as poor as mine...
This is how you receive the display:
As you can see, it looks different, but you only need to desolder R19 and R21 (both 10K resistors) and solder them back to R18 and R20.
The damn resistors are really tiny, but to demonstrate that anyone can do it, and at the risk of having people laughing at me, here is my result (position 19 ruined forever as a result):
Once you have this done, just connect the pins following the instructions in post #5, and there you go
PS: btw, it would be nice to control the brightness of the screen automatically according to the time (day/night). Is this something that can be implemented in the python document?
