Well, I'm a moron and have been bamboozled. I've purchased like 20 of these, because it said it was I2C: http://www.ebay.com/itm/282174165223?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
After reading up on it, I guess they're really SPI. Since I can't afford to ship them back to China, is there a way of doing a solder bridge on to make it work with I2C?
I was looking at the SSD1306 datasheet, and some things weren't making sense. For example, the "SCL" pin (on the header) was reading continuity on a pin of the ribbon that was supposedly NC according to the datasheet.
