The display is a 128×128 1.5" RGB OLED module, with a SSD1351 chip that communicates with the Pi over the SPI interface. I'm using the fbtft Linux driver for driving it, together with fbcp utility to copy the framebuffers. I have rotated the display 90° to make it fit with the dimensions of the Pi Zero better -- it only sticks a few millimeters on either side. Since this is an OLED, and not an LCD, the viewing angles are excellent and don't really change with the display's orientation.

I'm using a module and not a bare display, even though I'm making a custom PCB. That's because the OLED display needs quite a lot of components, including a voltage boost, and I'm not trusting myself to get all that right. It's also because I already have the module.

The size of this display, while a bit small, is perfect for the pico8 fantasy game console.
