Resistive touch screen IPS LCD 3.5" 480x320px GPIO for Raspberry Pi - Waveshare 12824

Description

Touch screen, resistive 3.5" display for Raspberry Pi with a resolution of 320 x 480 px. It works with any 40-pin version of theRaspberry Pi using the GPIO pins - as an extension for the minicomputer.

 

The device communicates through GPIO pins - as an extension for the minicomputer.

Raspberry Piis sold separately.

 

Connect to the Raspberry Pi

In order to start the screen, you need to plug athe screen into the GPIO pins on the Raspberry Pi.

 

 

Example of connecting the screen to the Raspberry Pi. 

Software
