Assembly Instructions for 2x8 connector

These instructions are for assembly of any display that uses a 2x8 connector:


The 2x8 connector is supported by TWILCD 40x2/40x4/RGB 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 2x8 dual row male header.

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, so that the pin numbering matches up.

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.
