NEW PRODUCT – OLED Breakout Board – 16-bit Color 0.96 w/microSD holder
NEW PRODUCT – OLED Breakout Board – 16-bit Color 0.96 w/microSD holder. We love our black and white monochrome displays but we also like to dabble with some color now and then. Our new 0.96″ color OLED displays are perfect when you need an ultra-small display with vivid, high-contrast 16-bit color. The visible portion of the OLED measures 0.96″ diagonal and contains 96×64 RGB pixels, each one made of red, green and blue OLEDs. Each pixel can be set with 16-bits of resolution for a large range of colors. Because the display uses OLEDs, there is no backlight, and the contrast is very high (black is really black). We picked this display for its excellent color, this is the nicest mini OLED we could find!
This OLED uses the SSD1331 driver chip, which manages the display. You can talk to the driver chip using either 3 or 4-wire write-only SPI (clock, data, chip select, data/command and an optional reset pin) or standard 8-bit parallel 8080/6800 which also permits reading pixel data from the display. Our example code shows how to use SPI since for such a display, its plenty fast. Inlcuded on the fully assembled breakout is the OLED display and a small boost converter (required for providing 12V to the OLED) and a microSD card holder. Our example code shows how to read a bitmap from the uSD card and display it all via SPI.
The logic levels for the microSD ard and OLED are 3.3V max. In order to make this breakout usable for bidirectional 8-bit and SPI interfaces, we left out an on-board level shifter. However, we include a DIP chip 75LVC245 8-bit level converter chip and our tutorial shows how to wire it to an Arduino so that you can use the breakout with 5V logic such as that of an Arduino. If you have a 3.3V logic level microcontroller system, you can skip the level shifter.

This is a fantastic new product.
I’m sure we’ll have a bunch of DIY Optimus Maximus keyboard projects in a very shirt future !
The other application that jumps to mind is “viewfinder”. Suggested optics, anybody?
I think someone needs to hook it up to the USB Microscope if they can. Even if they can do a section of the image, that would be good news. Maybe you should have a contest on who could do this the best.
These are really nice little displays. Excellent contrast and they appear very ‘sharp’. They’re easy to read despite their small physical size.
