Works well with a little reading.
I found that you DID NOT have to adjust the header file and only need to initialize the display with display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
Worked on both an Uno and a Mega.
Uno Pinout
SDA - A4
SDL - A5
GND - GND
VCC - 5v
Mega Pinout
SDA - 20
SDL - 21
GND - GND
VCC - 5v
The example code for the SSD1306 really starts to push the memory of the Uno, but the Mega has no issue loading the program.
Because it is an OLED, it will look dead until it has been initialized, which can be a bit confusing when you are first testing the screen. I thought I had a dud until I got it correctly initialized. Had no issues with 3.3v or 5v.
Tested with a 30k Thermistor.
