3.5 inch tft display with pcb for raspberry pi quotation
The touch screen LCD is ready with 320×480 resolution, 50 FPS (Frame per second). Resistive touch control is being supported by the Raspberry Pi OS or Raspbian (directly-pluggable). However, we will still need to install the driver for graphic display :)
However, there is a dedicated case/enclosure and a low-profile heatsink with a fan for this LCD to fit perfectly on the Raspberry Pi 4 Model B. The case has an opening for the LCD, and the low-profile heatsink with a fan keeps the Raspberry Pi 4 Model B protected and cool! You get a perfect console :) Don"t forget to remove the top lid/cover of the enclosure for the 3.5-inch LCD.
Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.
As we understand, Raspberry Pi 4 Model B delivers great performance and of course, more power will generate more heat as of all CPU :) So we need a way to install an additional heatsink to dissipate the extra heat. It will be better if we can have the option to add a cooling fan for active cooling. Well, this 3.5-inch touch screen LCD comes ready with the heatsink and cooling fan for you to use with the Raspberry Pi 4 Model B. it solves all the concerns.
The 3.5-inch touch screen uses the GPIO on the Raspberry Pi board, so it stretches out 2 pins as the power to supply the cooling fan on the low profile heatsink, and keep the Raspberry Pi board cool!
Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.
The Graphic driver is provided and can be downloaded for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux. Do follow the steps here: http://www.lcdwiki.com/MHS-3.5inch_RPi_Display
Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.

It is the cutest display for the Raspberry Pi. It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay. It"s designed to fit nicely not only to the Pi Model A or B but also works perfectly fine with the Model B+/2B/3B/4B.
*When working with Raspberry Pi 4, for the system image of Raspberry Pi after 2021-10-30, for example on Bullseye, please modify "dtoverlay = vc4-kms-v3d" to "dtoverlay = vc4-fkms-v3d" in the config file, otherwise it may fail to start. But on Buster, please comment out "dtoverlay = vc4-fkms-V3D" by adding #.
While googling for any info about lcd controller I came across this page: http://heikki.virekunnas.fi/2015/raspberry-pi-tft/, author managed to get from manufacturer patch file for kernel sources and tested it with 4.1.y - on which lcd worked. But still LCD replace HDMI, but I want to use this screen as additional for user interaction, while the bigger on HDMI as presentation monitor.
Since, fbtft has been merged with rpi kernel, so the fb drivers (including ili9341.c) was moved to fbtft_device driver (so the author of page can"t compile latest kernel with driver+patch).
So something about hardware, which I reverse engineered by the "hard way" - "grab multimeter and run through all LCD FPC pins and shift register pins"
I"m pretty sure about D/C (Pin 37 on LCD) and Reset (Pin 19 on LCD) pins by looking into driver code, but I can"t identify other signals (WR/RD/CS/etc...)

- Controller is not ILI9341/ILI9325 - those are for smaller displays (320x240, etc...), I guess this might be ILI9486/9488 because they are for 480x320 displays. But when I compared init with DS it does not fit right so LCD can have a clone of ILI9486/9488 ...
- Module use only SPI interface and two CE signals (CE0 for touch controller, CE1 for LCD shift registers - compared to others lcd modules, in KeDei module this is swapped),
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.

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).
Make sure the hardware connection is correct and connects fine. 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 was burnt incorrectly OR the TF card was in bad contact.
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. For large size LCDs, say, 10inch diagonal or more, another stand-alone power adapter is also required to provide power to the LCD.
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.
In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:
1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:
However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.
2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.
Enter sudo nano /etc/modules at the command prompt to edit the file. Go to the line for the ads7846_device parameters and move the cursor to the right to find it:
Now if you drag your finger around the screen, you will notice that the y axis (up and down) is correctly aligned with the motion of your finger. However, the x axis (left and right) is still inverted. To fix this, we need to install two more kernel modules, xinput and evtest. xinput is a Linux utility that will allow us to configure input device settings for the touchscreen controller, and evtest is an input device event monitor and query tool.
After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).
You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.
2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:
This will create a configuration file called /etc/ts.conf, which contains settings for variance and jitter that can be changed to optimize pointer response. See here for information about configuring ts.conf.
4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:
This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!
