This is a OLED display to install into a Gotek. There are three sizes: the 0.91 for the Gotek I, 1.1 for the Gotek II, and the 1.3 for Gotek Extended.
Both displays come with a 10cm 4-wire cable to hook up with the Gotek. No instructions are included; you are expected to know how to install and what the connections mean.
