3.5 inch touch screen tft lcd for raspberry pi factory

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

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 was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

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.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

It has 480x320 pixels with individual RGB pixel control and a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen. It is good for DIY projects such as mini gamepad, Desktop clock, appointment reminder, access control viewer and so on. The Raspberry Pi 3.5 inch Touch Screen can adjust the resolution by the software which also available for connecting Raspberry Pi 3 B+ directly, without additional power. (The RPI screen original resolution is 320×480).

The screen support 125MHz SPI signal input, the refresh rate is about 50fps which is enough to play the videos or games and display stable without flicker.

The 3.5 inch resistive Touch Screen can be directly inserted into any version of the Raspberry Pi (Raspberry Pi zero, zero w, a, A+, b, B+, 2B, 3B, 3B+) (The Case only suit for Pi 4).

The 3.5 inch RPI lcd display TFT Capacitive Touch Screen is a display module can be applied to Raspberry pi 3 B+ Pi Zero etc. It can be used as raspberry pi x window display terminals.

The RPI LCD Display TFT Capacity Touch Screen Modules used 28 pins out of raspberry pi 40 pin. When installing the module attention to align the first leg of the raspberry pi and LCD module.
