Graphic OLED display 128x64 Monochrome - 2.42"

A 2.4" wide area OLED display with 128x64 pixels

You way certainly noticed that OLED screen are quite tiny! So what to do if you need a larger OLED display?
You find the right product that will fit your need. This display have a 2.42" diagonal, and as it still use the OLED technology the display still offer à high readability. The display contains 128x64 individual white OLED pixels, each pixel can be turned on or off by the controller chip. Each pixel produce its own light so no backlight is required and offer a awesome reading contrast while saving power. This is a great graphic display!

The driver chip is a SSD1305 supporting three communication ways:

• 8-bit data,
• I2C
• SPI.

The SPI is the most obvious choice because it only requires 4 or 5 wires and offer a high bus throughput. The OLED requires a 3.3V power supply + 3.3V for logic levels (communication). The display is ship with a level shifter HC4050 chip that can be used to convert 5V logic down to 3V (so the display can be used with 5V board like Arduino). The included 220uF capacitor can be used on the 3.3V power supply to help the microcontroler 3.3V regulator with additional capacitance (as needed for Arduino board) ! 

The power need of the display depend on the number of pixels lit on the screen, 50mA can be used as an average value. The OLED driver contains a charging pump electronic to turns the 3.3V into a high voltage required to lit the OLED pixels.

The OLED display comes enclosed within a nice bezel and 4 mounting holes. This display does not come with header attached but we do toss in a stick of header you can solder on. The display is preconfigured for SPI communication. You can change modes from 8-bit to SPI or I2C with a little soldering, check out the tutorial for how to do so.

Getting started is easy! We 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.

Please note that OLED displays are made of hundreds of...OLEDs! That means each pixel is a little organic LED, and if its kept on for over 1000 hours it'll start to dim.To keept the display uniformly bright then turn the display off (set the pixels off) when it isn't needed.

For each order you will receive the OLED screen. Breadboard, microcontroler, wire and microcontroler board are not included (used for demonstrating the usage).

Please note that cable and code on back of board may vary but displays will work the same.
