Product description: Waveshare touch screen with 4'' (H) IPS 4'' Resistive LCD IPS 800x480px HDMI + GPIO for Raspberry Pi 4B/3B+/3B/Zero
4" Waveshare screen with800 x 480 pxresolution with touch,resistive. There is also a3.5 mm mini jack connectoron the board. It communicates with theRaspberry Pi 4B / 3B+ / 3B / Zero / Zero Wminicomputer viaHDMI and GPIO- the appropriate connectors areincluded.
The device communicates via HDMI (image) and GPIO pins (touch).
Example of connecting a screen withRaspberry Pi 4B.
Software
The manufacturer has prepared anoperating system with the drivers installed. The system should be unpacked by an appropriate program, e.g. WinZip, and uploaded to the card usingWin32 Disk Imager.
|
Detailed description of connecting and installing the drivers without changing the Raspberry Pi system and a picture of the finished system can be found onthe manufacturer's website. |
A screenshot ofWin32 Disk Imager, after selecting the system, just click Write button and wait for the installation process to be completed.
