3.5 inch tft display with pcb for raspberry pi b 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.

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.

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 #.

This small 3.5 inch touch screen Raspberry Pi Display module is designed especially for Raspberry Pi, using the latest Linux Core system. This is ideal for DIY anywhere, anytime and does not require any separate power source or case to hold it. The module sits right on top of Pi and an ideal alternative solution for HDMI monitors. The screen also comes with a stylus to interact with the small screen.

The UCTRONICS 3.5 Inch touch screen is the same size as the standard Raspberry Pi model B/B+, and well-mates with the Raspberry Pi boards. With a tiny size, vivid image, and responsive touchscreen, it is definitely ideal for portable devices and multimedia projects. It is a great replacement for a heavy and bulky HDMI monitor, keyboard, and mouse

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.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

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.

3. The calibration tool we will use is called ts_calibrate. We will also be using a program to check the results of the calibration called ts_test. In order to use ts_calibrate and ts_test, we must first set proper environmental variables. Enter export TSLIB_TSDEVICE=/dev/input/event0 into the command prompt, then enter export TSLIB_FBDEVICE=/dev/fb1:

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 calibration data will be written to a calibration file called /etc/pointercal. To view the contents of this file, enter cat /etc/pointercal at the root command prompt.

Drag the cross around the screen and observe how closely it follows your finger or stylus to test the accuracy of the calibration. Now press the “Draw” button to enter the drawing mode:

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!

- Case is a clear plastic. The kind that looks as if it will crack or shatter if dropped. It is not thick nor feels durable, but the board snaps into place and the top snaps with the bottom half in a solid manner.

- The wifi adapter worked out of the box and was able to stream 720p from an internet streaming site (and 1080p from a local network drive). My wireless router was in the same room about 4 feet away. Don"t know how well the wifi works if placed in another room.

- For those that think the SD card is not 4GB - it is. There is almost invisible print on the generic SD card that when looked at under bright light and maybe a magnifying glass has perhaps a serial number with the last few characters saying 4G or 4GB.

Also, the card is partitioned, so Windows will only see the first 1GB partition. With the SD card in your computer, go to Control Panel > Administrative Tools > Computer Management > Disk Management, you will find the SD card and all of its partitions adding up to around 3.75GB if your kit shipped with a 4GB card.

Putting it together was literally a snap. Installing your preferred OS may be an issue. The pre-installed software on the SD card is NOOBS. It will bring up a menu of different operating systems to choose. Choose the one you want, and it gets installed in a usable form on the same SD card. Upon completion, the system reboots into the OS or XBMC setup you chose.

After snapping the board, case, usb adapters for wifi and wireless keyboard, plugging in hdmi and power, nothing happened. A red light on the board lit up, but nothing else. I went online and after some googling, I found out that if no OS is recognized, nothing will display on your TV/monitor. I unplugged the power, took out the SD card and re-inserted, and the system booted into NOOBS.

I chose to install RaspBMC. The install went fine, the system rebooted to an XBMC screen that had a slight pink glow over the entire screen. More googling, and realized the board may not be outputting enough power through the HDMI port. There is info online for configuring a config file so more power goes to HDMI. I couldn"t get to this file from the SD card plugged into my laptop because Noobs makes this partition not viewable under Windows.

Anyway, I setup my wifi SSID and password in RaspBMC and the system automatically started updating itself. After completion and a reboot, RaspBMC died. It could not finish a successful reboot and mount its partition. It was unusable!!!

Shut it all down. Googled how to remove all partitions on an SD card from Windows command prompt with the diskpart function and formatted the SD card to one big FAT32 4GB partition. Went to the OpenELEC website and downloaded and installed the OpenELEC image for the Raspberry Pi. Booted into the XBMC version of OpenElec, configured wifi and other settings. Tested by watching both 1080p and 720p content streaming from a local network drive and from over the internet.
