Raspberry Pi 2.2 Inch GPIO display (without touch screen)

Description

This product is End Of Life. The PI-TFT22A module features a 2.2'display with 320x240 16-bit color pixels. This PI-TFT22A module refresh it's screen rapidly because the TFT module communicates with raspberry Pi in a high speed SPI interface ,this PI-TFT22A module can be used as Xwindow port ,displaying images or video etc. it plugs right in on top of your Model A+, B+ or Pi 2 and fits as HAT.

You can download configuration-free image or configurable packages, adjustable brightnes [level 0 -255], HAT compatible and Onboard buttons, you can load kernel modules to support GPIO KeyBoard function, almost all GPIO available on this board [non SPI 0,GPIO 18,GPIO 24,GPIO23],Very easily be other uses, IDROM has built initialization data to support Device Tree boot.

Feature

  • Character number: 320x240
  • Screen scale: 2.2'
  • Refresh rate: >20fps
  • Weight: 23.9g
  • module scale: 66x57x12(mm)
  • connect port: 2*20 Stacking Header
  • control interface: SPI
  • work voltage: 5V

Package Include

1 x Raspberry Pi 2.2 Inch GPIO display (without touch screen)

3. Reboot the Raspberry Pi and you will see the details on the screen.

Keyboard

  • It is easy to setup the keyboard,first you should install a software called "evtest" to detect the keyboard.

0. Install the package evtest:
sudo apt-get -y install evtest
1. Add following parameters to /etc/modules file.
gpio_keys_device pulldown active_low=0 keys=26:103,21:108,20:105,16:106
