If you've been diggin' Adafruit's monochrome OLEDs but need something bigger, this display will delight you! These displays are 2.42" diagonal, and very readable due to the high contrast of an OLED display. This display is made of 128x64 individual white OLED pixels, each one turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; Adafruit really like this graphic display for its crispness!
The driver chip, SSD1305 can communicate in three ways: 8-bit, I2C or SPI. Personally we think SPI is the way to go, only 4 or 5 wires are required and its very fast. The OLED itself requires a 3.3V power supply and 3.3V logic levels for communication. Adafruit include a breadboard-friendly level shifter that can convert 3V or 5V down to 3V, so it can be used with 5V-logic devices like Arduino.
The power requirements depend a little on how much of the display is lit but on average the display uses about 50mA from the 3.3V supply. Built into the OLED driver is a simple switch-cap charge pump that turns 3.3V into a high voltage drive for the OLEDs.
Each order comes with one assembled OLED module with a nice bezel and 4 mounting holes. The display is 3V logic & power so they include a HC4050 level shifter. They also toss in a 220uF capacitor, as Adafruit noticed an Arduino may need a little more capacitance on the 3.3V power supply for this big display! This display does not come with header attached but we do toss in a stick of header you can solder on. Also, the display may come in SPI mode. You can change modes from 8-bit to SPI or I2C with a little soldering, check out the tutorial for how to do so. Please Note: Metro not included! A microcontroller such an Arduino is required to use.
Getting started is easy! Adafruit have a detailed tutorial and example code in the form of an Arduino library for text and graphics. You'll need a microcontroller with more than 512 bytes of RAM since the display must be buffered. The library can print text, bitmaps, pixels, rectangles, circles and lines. It uses 512 bytes of RAM since it needs to buffer the entire display but its very fast! The code is simple to adapt to any other microcontroller.
