 +Cut or Snap a length of two male headers 9 pins long and one 3 pins long. Insert into corresponding positions (on the bottom of the board) and solder each pin. Be sure to leave the row of holes on the edge of the board open where there are two sets of 9 holes. This is where the TFT screen is soldered. 
 + 
 +**Tip:** Inserting the headers into a breadboard and then placing the board on top can make this process easier. 
 + 
 +**Note:** If you are using stackable headers, use them here instead of the standard male headers.

 + 
 +The TFT screen should have headers pre-soldered into place. Insert into the open row of holes on the right edge of the shield and solder each pin from the bottom. 
 + 
 +**Note:** For a less permanent solution, use a row of female headers so you can remove the TFT screen as needed.

 +=====Code:​=====
 +
 +See Examples->​Adafruit_ILI9341->​graphicstest - NOTE: This uses a modified version of the Adafruit_ILI9341 library (that is still compatible with other platforms), ensure that the example references the Oak otherwise you have a conflicting library installed.
 +
 +=====SD Card:=====
 +To use the SD Card slot use wire to connect the corresponding pins on the LCD to the PCB.
