Sometimes you use the the Raspberry Pi with 3.5 inch touchscreen , but sometime you don't use them together. In this situation , you need a case which both suitable for Raspberry Pi alone or with 3.5 inch touchscreen. This is the reason we provide this new case -- for the people use 3.5 inch screen more convenient: When you use the touchscreen , just remove the cover board and fan; When you don't use the touchscreen , you can use the cover and fan , which become a normal case.
Please note that you can't use the 3.5 inch touchscreen and cooling fan at the sametime !
1. One case for two use :
1). This case suport install 3.5 inch touchscreen , and need to remove the cover board and can't use the fan in this using way.
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.
( You can't use the 3.5 inch touchscreen and cooling fan at the sametime ! )
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.
-480×320 pixel resolution, better display.-Driverprovided (works with custom Raspbian directly).
-Supports any revision of Rasp Pi (directly-pluggable).
-Designed for Raspberry Pi, an ideal alternative solution for monitor.
-Support software keyboard (system interaction without keyboard/mouse).
-Provides the best available protection/accessibility for Model B, Protect and secure your Rasp Pi from shocks, scratches and dust.
How to install the 3.5 inch touchscreen :
1). Install the Raspberry Pi on the base board
2). Please stick the pad on the back of 3.5 inch touchscreen , then insert the 3.5 inch touchscreen on Raspberry Pi by GPIO pin correctly ( don't be malposed )
3). Install the cover board Parameter:

About the system of 3.5 touch screen
The touch screen need to configure the driver for touch function , otherwise you can not use it by your own system.
Here we provide the method to configure for Raspbian system :
Step 1: Download the Raspbian IMG Package included:1 x 3.5 inch Touch Screen
Step 2: Burn the system image
If you don't know how to do that,you can refer to the Raspberry Pi office tutorial
Step 3: Open terminal(SSH) and install the driver on RaspberryPi
(tested on RaspberryPi 3B+,3B,2B,2B+,1B,ZERO)
sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
Wait A Few Minutes, when the system reboot ok, you can see that.
You can also download the system image which we already configured well by following links :
1. for Raspberry Pi 3 :
2. for Raspberry Pi 3 Modle B+ :
or refer to configure it by this link :
1 x Protective Case
1 x Touch Pen
