Description
Touch display, resistive 4" for the Raspberry Pi with a resolution of 800 x 480 px. Works with every 40-pin version of Raspberry Pi via the HDMI connector and the GPIO pins - necessary connectors included in the package.
The device communicates via HDMI adapter (image) and GPIO pins (touch).
Connecting to the Raspberry Pi
In order to run screen, put the device on the GPIO pins of the Raspberry Pi and mount the HDMI connector.
Example of connecting the screen tothe 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.
