I recently purchased a LANDZO 3.5 Inch Touch Screen 320480 for Raspberry Pi 3 Model B (3.5 inch) and when I un-boxed it I realized that it had a large GPIO block on the back of it. This GPIO block makes it much thicker than it would other wise be. I can not de-solder it because it is attached firmly to a board that is attached to the display.

Can this GPIO block be removed without ruining the display? And if it is possible, how do I connect the display to RPi zero or RPi 3 when this GPIO header block is detached?

Thanks for any pointers on this,

BR, G.Gordon

  • are you talking about the pin header? ... you can just cut it up using good quality wire cutters – jsotola May 1 '18 at 17:29
  • Yeah, I must be talking about the pin header. It is huge and triples the depth of an otherwise narrow screen. It is like a black plastic rectangular block with pairs of holes in it that receive the GPIO pins on the RPi3 board. Can I just break this black part off? – Wobot May 1 '18 at 17:38
  • The part I want to remove is the "female" part connected to the back of the display. – Wobot May 1 '18 at 17:41
  • You do realize that is how the screen gets power, and works as a touch screen? From the looks of things, it uses 8 pins, not including power and ground. You will have to do something else to make those connections if you remove the plug. The ribbon cable is just display input. – goldilocks May 1 '18 at 18:08
  • I am aware that those pins can provide power but I wasn't sure about the touch screen. I am hoping to supply power by a micro usb port with an on/off switch that I will solder on the board. My project will not require a functional touch screen so I will leave it disconnected. – Wobot May 1 '18 at 18:12
