This is the first in a series of blog entries which cover the displays included in the Kemo Electronic S043 lucky bag sold at Maplin and describes the use of them. The series went under massive reorganisation in 2016 with the addition of new displays plus a new overview picture.

This lucky bag typically costs £4.99 and contains 10 assorted displays. Each bag comes with a variety of different displays with balanced distribution, and generally a bag 2-3 large displays, 2-3 medium displays and 4-6 small displays, so you won't find one bag containing entirely HD44780-compatible LCDs and another containing 7-segment displays only. I wouldn't recommend just buying them on the website as you don't get to see what's in the bag unlike in store. The displays aren't individually packaged and they have the potential to damage each other in the packaging so you'll want to check for that before you buy.

Displays are numbered below in row-column format e.g. 4-1 is the tiny 7-segment display in the bottom left corner.

Users should test all LED displays before building a stripboard/PCB circuit for them.

2-5 OLED Display
The OLED uses an SSD0303 and gives you many interface options including parallel, SPI and i2c. The pinout of the OLED can be found on page 44 of that datasheet as well as the leaflet included with the pack of assorted displays. The OLED is also easily dimmable through software commands, unlike some OLEDs which require modification.
The OLED is blue - the shade of blue it uses looks nice in real life and is a deeper shade than in the photo above - the screen burn-in example below is closer to the real colour. The right way up is with the tab at the top which allows you to fold the tab behind the OLED and have the breakout board with the pins at the bottom.
Use of an adapter board like the one shown in the photo (search for 'tft to dip' on eBay) is essential if you want to use the display on breadboard or stripboard - you can't just solder jumper wires to the connections and bend them to fit in a breadboard since the connections are fragile and you will break them if you do this.
Note: These OLED Displays are very vulnerable to screen burn (particularly on the brighter settings), unlike the Winstar OLEDs sold by Rev-Ed. Running the clock demo for more than a few minutes on the bright setting or a few weeks on the dimmest setting will cause visible screen burn-in.
