Description
Touch screen, resistive 3.5" for the Raspberry Pi with a resolution of 320 x 480 px. Works withRaspberry Pi, version 3B, 2B, B+, Zero and Zero W via the GPIO pins - as cap for minicomputer.
The device communicates through GPIO pins - as a cap for minicomputer.
The Raspberry Piis sold separately.
Connection to the Raspberry Pi
In order to run the screen, you need to put a screen on the GPIO pins of the Raspberry Pi.
Example of connecting the screen to the Raspberry Pi.
Software
The manufacturer has prepared the operating system with the installed drivers. The system should be unpacked using an appropriate program such as WinZip and upload to the card usingWin32 Disk Imager.
Screenshot of the programWin32 Disk Imager, when you select the system, just press the Write button and wait until the installation process is completed.
