Insert the header that came with the PiTFT into the PCB. Use a piece of fun tac to hold the header in place while you solder.
Solder the pins on the GPIO to seure the header to the PCB. The solder joints should look like little herseys kisses.
Remove the tac from the GPIO header. Ball it up and save it for the next project, it's served it's purpose!
Insert five tactile switch buttons into the designated spots on the PiTFT PCB. They snap fit and will hold in place. Secure the PCB to a panavise jr and solder the buttons to secure them.
Snip the excess leads from the buttons the PiTFT PCB. These bits are sharp and could scratch the components.
Disable GPIO 18 Lite
By default, the 2.4' PiTFT uses GPIO 18 to turn on/off the backlight on the display. In this build we're using GPIO 18 as a input button, so we need to cut the trace located on the back of the PCB, labled #18 Lite. Use a hobby knife to cut the trace.
With the GPIO header and buttons soldered, go ahead and flip over the display so the two parts are side by side.
Use your nail or hobby knife to peel the orange colored sticker backing. Remove and peel both pieces.
