Introduction :

We design the case for install 3.5 inch touch screen.When you use the screen, please remove the cover of case. The cover can install the cooling fan (the fan is not include), so when you don't use the screen , you can use it with cooling fan. We also design a holder with cooling fan, which allow you use the screen with cooling fan at the same time. You can choose the option accordin to your need.

The touch screen connect to Raspberry Pi by GPIO pin only , please don't use the HDMI interface when you use the touch screen.

About Case :

2). When you don't use the 3.5 inch touchscreen , it is a general case with cooling fan.

2.Full access for Raspberry Pi :

We leave every hole for SD card , HDMI , AV , Ethernet , USB , POE , Camera , MIPI DSI ports.

3.Support cooling fan :

You can install the cooling fan on the cover board , which make the best heat dissipation and extend the using life of Raspberry Pi.

4.Hange hole on the bottom:

We make 2 hole on the bottom so that you can hange the case on the wall or something else . This design is very convenient when using the 3.5 inch touchscreen.

5.There are Black / Transaperent color to chose for the case.

6.How to assemble the screen and case

2). Insert the 3.5 inch touch screen on Raspberry Pi by GPIO pin correctly ( don't be malposed )

3). Install the cover board

About 3.5 inch Touch Screen :

You need to configure the driver to use this touch screen, support Raspbian/Ubuntu/Kali-linux system.(Ubuntu just support RPI 3B/3B+, doesn't support RPI 4B )

Please use our recommended system for touch screen. If you use other systems, it may not have touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with our touch screen.Please use our recommended system for touch screen.
