Step 5: LCD Socket

You will be installing a 20-pin socket into P1. This is where the LCD module will connect with the board.

Tools Needed

  • Soldering iron

Parts Needed

  • 1 x 20-pin single-row socket


  1. Install the 20-pin header socket into the P1 footprint on the top side of the board.

  2. Hold it down with a piece of tape to keep it from falling out when the board is flipped.

    Mount the socket flat against the board

    The header must connect to the LCD, so it needs to be just right.

  3. Solder the header on either end to hold it in place before soldering the rest of the pins.

  4. Solder the rest of the pins.
