Introduction
7 inch Capacitive Touch Screen LCD, HDMI interface, supports various systems
Revision
For revisions under Rev2.1
- For the Raspberry Pi, comes with Raspbian driver (works with your Raspbian directly), and Ubuntu image
- When work as a computer monitor, touch function is unavailable
Rev2.1 New Features
- Standard HID protocol, easy to be integrated into your system.
- For the Raspberry Pi, supports Raspbian, Ubuntu, Windows 10 IoT, single touch, and driver free.
- When work as a computer monitor, supports Windows 10/8.1/8/7, five-points touch, and driver free.
How to Distinguish
- See the backside of your LCD. The Revision number "Rev2.1" printed means that the LCD firmware is Rev 2.1.
- However, "Rev1.1" printed on the backside doesn't mean that the LCD firmware must be Rev 1.1. Generally speaking, a LCD shipped after January 1, 2016 may be a Rev 2.1 one, although it was printed "Rev1.1".
Note: The only difference between Rev 1.1 and Rev 2.1 is the firmware, but hardware solutions, placement and routing are all the same. (PCB printings might be different due to different production batches.)
You can verify the firmware by these steps:
1. Using Raspberry Pi: Connect the LCD to your Pi (HDMI Port of LCD -> HDMI Port of Pi; USB Port of LCD -> USB Port of Pi; 5V~2A power supply). Download the image, e.g. Raspbian 2015-11-21 jessie or Raspbian 2015-05-05 wheezy, from Raspberry Pi web site. Write the image to a TF card and add the following code to the end of /boot/config.txt:
max_usb_current=1 hdmi_group=2 hdmi_mode=1 hdmi_mode=87 hdmi_cvt 800 480 60 6 0 0 0
Save and connect the TF card to your Pi then power up. If touch works, that means the firmware revision is Rev 2.1.
2. Without Raspberry Pi: A PC (Windows 10 / 8.1 / 8 / 7) is required which cannot connect with other display device. Connect the LCD to your PC (USB Port of LCD -> USB Port of PC; HDMI Port of LCD -> HDMI Port of PC. Please first connect the USB Ports then connect the HDMI Port). If a new touch drive is recognized by Windows, that means the firmware revision is Rev 2.1. In this case, after the driver successfully installed, you can use the LCD as a human interface device.
- If the touch function doesn't work properly after these steps, the firmware revision is often Rev 1.1, which can also work by other methods, see Rev 1.1 Manual.

FAQ
{{{5}}}
Make sure the image in TF card is burnt correctly.
The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image were burnt incorrectly OR the TF card were in bad contact.{{{5}}}
