Haha, I must be blind or need to get my eyes checked out or something. I ask around people keep mention the rar file, where is it? I couldn't find it on the Amazone link.
Thanks for pointing that out. You think the labelling is confusing as well? Thanks. I thought it was just me.

The SSD1331 datasheet and board schematic are in the rar. In SPI mode, data goes in on the D1 pin of the chip which is labeled SDA on the board. Clk goes in on D0 which is labeled SCL. I think you should connect SDA to MOSI, SCL to SCK, and CS to CEO. There is no data output from the module so nothing connects to MISO. The DC pin chooses between Commands or Data and should be connected to a GPIO pin.
