-====== Which LCD to use ====== 
-

-This backpack will work with any '​standard'/'​classic'​ **character** LCD. It does not work with **graphic** LCDs. Character LCDs come in sizes ranging from 8x1 (8 characters, one line) to 40x4 (40 characters, four lines). The backpack will also only fit LCDs that have a single line of pins at the top, not the ones that have a 2x10 or 2x8 connector on the side. Those are much rarer these days but just keep a look out for that! 
- 
-====== Assembly ====== 
- 
-Putting together the backpack onto an LCD is a quick process, and should take only a few minutes with a soldering iron. 
- 
-===== Parts check ===== 
- 
-Verify you have everything in the bag, there should be an assembled and tested PCB, a 2-pin and 3-pin 3.5mm terminal block. The backpack does not come with header or an LCD.  
- 
-===== Terminal blocks ===== 
- 
-The [[http://​www.ladyada.net/​wiki/​partfinder/​terminals|terminal blocks]] allow you to easily attach and remove the LCD from your wiring, which we think is awfully handy. If you dont want the terminal blocks (they stick out a bit) you can always skip this step. 
- 
-[[http://​www.ladyada.net/​wiki/​partfinder/​terminals|The terminal blocks come in 2 and 3-pin pieces]]. Slide them together. 
- 
-Place the blocks over the corner area of the backpack so that the holes stick out (unless for some reason you want them to face the other way) 
- 
-Solder them into place 
- 
-===== Attach LCD ===== 
- 
-Next we will attach the backpack to the LCD. First we must put header onto the LCD, if you bought the LCD from us, it will come with a stick of header. Otherwise, pick up some [[http://​www.ladyada.net/​wiki/​partfinder/​header#​male_header|standard 0.1" male header]] 
- 
-These photos shows a 10K potentiometer,​ you can ignore it

- 
-If the header is too long, just cut/snap it short so that it is 16 pins 
- 
-Next you'll need to solder the header to the LCD.You must do this, it is not OK to just try to 'press fit' the LCD!

-{{  http://​www.ladyada.net/​images/​arduino/​lcdtut/​headersize_t.jpg ​ |http://​www.ladyada.net/​images/​arduino/​lcdtut/​headersize.jpg}} 
- 
-The easiest way we know of doing this is sticking the header into a breadboard and then sitting the LCD on top while soldering. this keeps it steady.

- 
-We will do this in a permanent fashion. If you think you would like to remove and replace the LCD at some time, you can use female header
