EA DOG 3V or 5V displays from

The EA DOG series displays and backlights has been specially developed for a +3.3V and +5V voltage supply. Unlike other displays this series allows you to select the display type and the backlight illumination.  This way many combinations and personalized effects can be created with standard components. Simply clip the display and the backlight unit together and up to 63 possible combinations are available. The alphanumeric displays are available in 1x8, 2x16, 3x16 or 4x20. we now also have the DOG graphic displays with 132x32, 102x64, 128x64, 160x104, 240x128 pixels

Each type comes in STN yellow/green, STN reflective, STN negative blue, FSTN blue, FSTN positive and negative. See selection table below. There is also a choice of 5 different backlights (green, red, amber, blue and white) and now also a full RGB backlight. See selection table or simulator software below.

Arduino UNO display shield for our DOG displays

Unpopulated Arduino shield for the popular EA DOG displays are now available. The support documentation includes circuit diagrams, EAGLE PCB layouts, component placements, initiation sequences and sample programs for operating the display on an Arduino Uno. Three different size shields are available. There is a display shield for the EA DOGM081-A (1x8), EA DOGM162-A (2x16) and EA DOGM163-A (3x16) with ST7036 controller. The 2nd shield is for EA DOGM132-A (132x32), EA DOGM128-6 and EA DOGL128-6 (128x64) graphic displays with ST7565R controller. The 3rd shield is for the EA DOGS102-6 (102x64) graphic display with UC1701 controller.
