They are 84x48 pixels, so can be used for text or graphics, like charts for data-loggers. I have one on a board from SparkFun.&lt;ref&gt;http://www.sparkfun.com/products/10168&lt;/ref&gt; I plan on connecting it to my Arduino Pro Mini and/or some PICAXE. It uses a serial interface, like SPI but with an extra select between data/commands. So, I plan to use the built-in SPI functions of the Arduino, but I might also consider some libraries including one I found for PCD8544, so that I don&#039;t have to keep track of special functions for the board like initialization.<br /> <br /> The SparkFun PCD8544 uses 3.3V, not 5V, for power and signal levels. 5V levels might damage the controller.<br /> <br /> ==References==<br /> &lt;references /&gt;</div>
