===Screen===
*If it's the first time for you to use this LCD module , please download the device driver for Raspberry Pi ,you can download the file from the following link http://www.52pi.net/forum.php?mod=viewthread&tid=1363&highlight=rtc
*If you are done download the device driver ,copy and past them into 'pi' folder in Raspberry Pi
 [[Image:2.2TFT_tech1.png|800px]]
*type<code>sudo tar -jxpvf TFT-stable-Build-20150424.tar.bz2 -C</code> to extract the device driver file
 [[Image:2.2TFT_tech3.png|800px]]
* modify modules file in /etc folder ,you can type <code>sudo vim.tiny /etc/modules</code> to open this file.To modify the file you should follow the picture beside
<code>
fbtft dma
fbtft_device name=rpi-display rotate=270 speed=64000000 gpios=dc:24,reset:23,led:18
</code>

 [[Image:2.2TFT_tech6.png|800px]]
*If you have finished above step ,then ,reboot the Raspberry Pi,and now you will see the reboot details is on the screen

===Keyboard===
*It is easy to setup the keyboard,first you should install evtest to detect the keyboard
*modify modules file in /etc folder like following picture ,just add code
<code>gpio_keys_device pulldown active_low=0 keys=26:103,21:108,20:105,16:106</code>
