Scouring the internet for a decent OLED display, I came across this one from buydisplay.com. It's a 128x128 RGB display, with 1.5" diagonal measurement. The controller, SSD1351, supports a 8, 16, or 18 bit parallel interface, as well as SPI for communications. It seemed perfect for the projects I had in mind. Most breakout boards out there only take advantage of the SPI pins of the controller, and at least one of my projects would require access to the parallel interface, so I decided to just build my own board to suite my needs. Hopefully someone else finds it useful.
Wow, that's much fewer components than I expected! That boost converter looks sweet.
