*For 4inch RPi LCD (A), run the command:
 
sudo ./LCD4-show
 
*For 5inch HDMI LCD, run the command:
 
sudo ./LCD5-show
 
 
 
Then, wait a few minutes, the system will restart automatically. When finished, the RPi LCD is ready to use.
 
 
 
To switch to HDMI display, run the command:

FAQ

 Answer:
The LCD must have a driver installed for normal use. For details, please refer to the relevant introduction in the user manual.

{{{5}}}


 Answer:
Since the Raspberry Pi image and version are frequently updated, if you encounter a situation where the LCD cannot be used normally, please download the latest version of the image provided by us or from the official website of Raspberry Pi and install the latest driver provided by us.
  • Make sure the hardware connection is correct and the contact is good.
  • Make sure that TF card programming is normal.
  • When the Raspberry Pi starts normally, the PWR light is always on, and the ACT light is flashing. If it is found that both lights are always on, it may be that the TF card is not successfully programmed to the image or the TF card is in poor contact with the Raspberry Pi.
  • It is recommended to use a 5V 2.5A power adapter for the Raspberry Pi. If the Raspberry Pi is powered by the USB port of the PC, the Raspberry Pi may not be able to start normally due to an insufficient power supply.

Anti-Piracy

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:

Beware of knock-offs

Please note that we've found some poor copies of this item in the market. They are usually made of inferior materials and shipped without any testing.

You might be wondering if the one you're watching or you've purchased in other non-official stores is original, feel free to contact us.
