Assembly Instructions for 1-14+2 connector

These instructions are for assembly of any display that uses a 1-14+2 connector:

Note that pins 15 and 16 come first, then pins 1-14. If the order of pins for your display is instead 1-16, you should go to the 1x16 pin assembly instructions.

This kind of pinout is common on many displays from the manufacturer Sunlike. The instructions can also be used to assemble other displays that have the same pinout.


The 1x14+2 connector is supported by TWILCD (standard) ONLY.


The display should be connected as follows:

Please see the compatibility page for an overview of supported displays.


To assemble this kit, you will need:

  • A soldering iron
  • Solder
  • A wire cutter (a diagonal type that allows you to cut the wires as close to the soldering points as possible is best)
  • Helping hands or clips to hold the PCB in place when soldering (a vise will also work)


  • A multimeter
  • Desoldering wick
  • Solder sucker
  • Protective glasses

See the equipment page for more details.

Step 1

You will need a single row male header, 16 pins long. You can break off 16-pins from a standard male header strip (either by hand or with wire clippers.)

The long part of the legs should point out and the short part should go into the holes to be soldered in place.

Use a clip or a piece of masking tape to hold it in place, flip the board over, solder in one pin, then check orientation.

Once orientation is ok, solder in all the remaining pins.

Step 2

Insert the board to the back of the display like so:

Note that the two first pins (marked K and A are left open). Now solder the board in place. The end result should look like this:

Step 3

Finishing touches: The pins from the header that attaches the display to the TWILCD board stick out a bit. You may want to clip them off (close to the solder point) before using the display. When doing this step hold your hand over each pin as you clip it and use eye protection as small pieces of metal may fly out at very high velocity.

Congratulations, you have now assembled the TWILCD display. Head over to the Usage page for further instructions.
