In this tutorial, we are going to interface a 3.5-inch TFT display with Raspberry Pi Zero Wdevelopment board. Although Raspberry pi zero itself has an HDMI output that can be directly connected to a Monitor, but in projects where space is a constrain, we need smaller displays. This TFT touch screen display can be easily interfaced to the Raspberry Pi to display the system console, movies, and images, as well as control a relay board and other devices at your fingertips. We’ve used software like MobaXterm or putty to connect to the PC remotely in past tutorials. Here, we are going to use MobaXterm software to install the required drivers for interfacing TFT display with Raspberry Pi Zero W.

This TFT LCD display has a 3.5-inch resistive touch screen display and is compatible with any hardware of the Raspberry Pi family. This 3.5" TFT display has 480x320 pixels with a 16-bit resolution and resistive touch option. It can fit directly on top of the Raspberry Pi Zero W board and gets powered from the Vcc pin, the display communicates through SPI protocol with the Pi. Additionally, you can also use the HDMI port on the Pi to connect it to another display as well. It is designed for Raspberry Pi Zero/Pi 2 /Pi 3 Model B / B+ and can also be used on other hardware platforms which have SPI interfaces. The highlights of this display module is that it supports plug and play without rebooting the Pi and the SPI speed runs as fast as 32MHz to support games and videos.

There are 26 pins in TFT RPi LCD display. It"s used to establish SPI communication between the Raspberry Pi and the LCD, as well as to power the LCD from the Raspberry Pi"s 5V and 3.3V pins. The description of pins is shown below.

It is very easy to connect Raspberry Pi Zero W with a 3.5” TFT LCD display. There are 40 pins on the Raspberry Pi Zero W, but only 26 pins on the LCD, so make sure you connect the pins to your Pi correctly. A strip of female header pins on the LCD will fit snugly into the male header pins. To establish the connection, simply align the pins and press the LCD on top of the Raspberry Pi zero W. When everything is in place, your Pi and LCD should look like the one given below.

After you"ve connected the LCD to the Raspberry Pi Zero W and power on it, you"ll see a blank white screen on the LCD which is due to the fact that no drivers for the linked LCD have been installed on the Pi. So, open the Pi"s terminal window and start making the necessary adjustments. Here, we are going to use MobaXterm software for connecting Raspberry Pi Zero W but you can use PuTTY or any software which is most comfortable for you.

It"s expected that your Raspberry Pi already has an operating system installed and can connect to the internet. If it is not then you can follow our previous tutorial Getting Started with the RASPBERRY PI ZERO W – Headless Setup without Monitor. It"s also assumed that you have access to your Raspberry Pi"s terminal window. In this tutorial, we are going to use MobXterm in SSH mode to connect it with Raspberry Pi Zero W.

Step-2: In this step, we are going to enable SPI connection for Raspberry Pi Zero W. To enable SPI communication, select ‘Interface options’, and then select ‘SPI option’. Then click on "yes" to enable SPI interfacing.

Step-3: Now as we have enabled the SPI interfacing, in this step, we are going to install touch driver in our Raspberry Pi Zero W. You can install the touch drivers using the below command:

Step-5: Now, restart your Raspberry Pi Zero W. When the Raspberry Pi Zero W restarts, you will see the boot information on the LCD display before the desktop appears, as shown below.

I would like to add one thing at the end of this tutorial that while doing this interfacing, I faced a problem related to OS. TFT display interfacing with Raspberry Pi Zero W was not working on Raspberry Pi OS LiteandRaspberry Pi OS with desktopbut when I used the Raspberry Pi OS with desktop and recommended software then TFT display interfacing with Raspberry Pi Zero W worked as expected.

This is how you can interface Raspberry Pi Zero W with a 3.5 inch TFT Raspberry Pi display. In our next tutorials, we are going to interface different sensors with Raspberry Pi Zero and you will see some amazing DIY projects using Raspberry Pi Zero W. I Hope you"ve enjoyed the project and learned something useful. If you have any questions, please leave them in the comment section below or use our forum to start a discussion on the same.

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.

This microcomputer can not boast of high performance. Still, it has a compact size, ultra-low power consumption, and can perform those tasks, for which implementation Arduino or ESP8266 platform will not be enough. The power of the microcomputer of Raspberry Pi 3 level or its more expensive and productive brothers will be excessive.

The origins of the Orange Pi line of microcomputers go back to 2014 when Chinese company Lemaker released its clone of the increasingly popular Raspberry Pi, the Banana Pi M1 single-board computer.

Shortly after that, there was a split among the developers. One part continued to produce specialized and no longer positioned for the home user “development boards” under the Lemaker brand. SinoVoip continued to develop a line of Banana Pi microcomputers, the total number of models in which has already exceeded a dozen. Finally, Shenzhen Xunlong Software, managed by Steven Zhao, created the Orange Pi line, focusing on low prices.

The tactic proved to be a winner – today, Orange Pi is one of the most famous brands among single-boarders, and the number of sales of the Orange Pi Zero model alone in the Shenzhen Xunlong Software store has exceeded 8000 copies since its release in November 2016.

26-pin expansion board: GPIO (General Purpose Input/Output Interface), Power (+5V, +3.3V and GND), some pins can be used as UART, I2C, SPI or PWM 13 pins, 2 x USB, IR, AUDIO(MIC, AV)

Orange Pi Zero has two GPIO combs, one for 13 pins and one for 26 pins. The 13-pin comb is used to connect the Interface Board – an expansion board with additional USB ports, analog AV output, microphone, and IR port. The 26-pin comb is available for user peripherals, and its pinout is shown in the illustration above.

The package does not differ from that of the Raspberry Pi 3. The electronic components are sealed in anti-static bags and packed in separate cardboard boxes with branding. The plastic case is shipped unpackaged in a simple polyethylene bag.

Orange Pi Zero has one USB 2.0 port and a 100 megabit Ethernet interface with PoE (Power over Ethernet) technology, which allows you to power the device directly through the Ethernet cable. This technology is most often used in video surveillance and requires a PoE-enabled network switch.

The largest chip is the Allwinner H2+ SoC, and next to it is a 256MB or 512MB RAM module, depending on the Orange Pi Zero version. And the small square chip is the Allwinner XR819 chip, a cheap and compact Wi-Fi module. Usually, Wi-Fi modules are combined with Bluetooth modules, but the XR819 does not support Bluetooth. You have to keep it in mind and if you are going to use Bluetooth-connected peripherals, make sure you buy a USB adapter beforehand.

The GPIO interface is represented by two combs: a 13 pin one for the expansion card connection and a 26 pin one for everything else. The 26 pin comb is not unsoldered by default: the person who wants to use the GPIO periphery is supposed to solder the connectors himself and decide whether they will be directed upwards or beveled corner ones.

Since there is no HDMI interface (as far as I understand, it is not supported by the Allwinner H2+ chip), the only way to connect Orange Pi Zero to the screen is to buy an adapter cable from AV plug to analog “tunnels”. Or connect a small TFT display to the GPIO.

Nothing is interesting on the backside of the expansion board, just another sticker with a barcode. The numbers on it indicate that the expansion card was produced before the Orange Pi Zero itself. In general, it makes sense – not every buyer of microcomputers gets additional accessories.

Orange Pi Zero is rather undemanding to the power supply – the microcomputer consumes about 300 mA, which means that its working power supply of 1 A will be enough. Of course, you should take into account the consumption of connected peripherals – if you connect several hard drives, then 1A is not enough for everything.

As for the heating and cooling, in this case, everything is not clear. Allwinner H2+ is noticeably warm. The chips made by Allwinner Technology, in general, do not belong to the number of colds. But there is a software bug in the Armbian operating system (more about it later), which causes incorrect display of SoC temperature on Orange Pi Zero revision 1.4 – and this is the latest revision at the moment, and it is on sale. This bug, by the way, is honestly reported on the distribution download page.

At zero CPU load, Armbian shows a temperature around 140°F. It is logical to suppose that if you load the processor, then at such starting conditions, the temperature will instantly fly beyond 176°F, and hard trolling will start. But this does not happen. The temperature rises, but only slightly, no trolling starts, no smoke comes out of the chip :).

Until this bug is fixed programmatically in Armbian, it is impossible to track the SoC’s real temperature. It is not superfluous to install radiators – here, the copper ones which I used for cooling Raspberry Pi 3 will do.

Before using the microcomputer, let’s assemble it in one piece. The correct way to start is to glue the heatsinks to the SoC and memory module, but I didn’t think to buy them beforehand, so I assembled without them.

After that, we put the Orange Pi Zero board with GPIO pins on the Interface board socket. By the way, there is no access to the 26 pin GPIO interface of the Orange Pi Zero board from the case as well as there is no place for the complete Wi-Fi antenna. Therefore the antenna must be disconnected before assembling the board, and if you plan to work with GPIO – you should not assemble the microcomputer in the case at all.

And a couple of words about how to take the whole construction back apart. The Orange Pi Zero board sits pretty tightly on the Interface board socket, and you can’t get it out with bare hands. You need to put some thin and hard object under the board and use it as a lever.

Orange Pi developers offer you to download several Linux distributions, of which there are even variants like OpenWrt and Zeroshell for routers and other network equipment.

So, if you are not confused by the well-known problems of the Armbian distribution kit for Orange Pi Zero – don’t hesitate to download and install it, especially because there are no better alternatives at the moment.

The memory card with the recorded system has to be installed into Orange Pi Zero, then connect the microcomputer to the local network with an Ethernet cable and apply power.

After that, you can monitor temperature (incorrectly displayed, but still), CPU load, uptime, and other indicators at http://ip-address-orange-pi:8888, accessible from any device within the local network.

Despite what was said in the notes to the Armbian release about poor support of the Wi-Fi module and the fact that when assembling the microcomputer in its case, I had to disconnect the external antenna, the Wi-Fi connection quality can be assessed as quite satisfactory.

A microcomputer can be turned into a handy network audio player. You can find details of such a project on the Internet by searching for “Logitech Media Server” or “Squeezelite”. I may write a separate post on this topic in the future.

Because of its low price Orange Pi Zero is perfect for a print server implementation based on the CUPS package. In this case, the price of the device is half of what you would pay for an off-the-shelf print server in a store.

By connecting a webcam via USB, you can turn Orange Pi Zero into an IP-camera for video surveillance, and the PoE support adds to the convenience: if you have a PoE-compatible switch, you will need to pull only one Ethernet-cable to the makeshift camera for power and data transmission. The feasibility of building such a device from scratch is questionable because the cost of the factory IP-camera in China is roughly equal to the cost of a set of Orange Pi Zero and a webcam. But if there’s a webcam at home that’s already gathering dust, this is a good opportunity to give it a second life.

You can make the device a smart home server by installing the Domoticz / Home Assistant / OpenHAB / MajorDoMo platform on Orange Pi Zero. There will be a separate post about it in the future.

These are the simplest and most obvious options. It is possible to think up more highly specialized ways of using it – for example, I’ve seen on the web someone had put together a system based on Orange Pi Zero to control the automatics of aquariums.

Orange Pi Zero isn’t a high-end performance contender and can hardly be used for resource-intensive multimedia tasks, but it is very handy for building inexpensive and utilitarian devices aimed at one particular function – like the above-mentioned print-server, hiking NAS, or smart home system control head-device.

The low cost makes it a good option for beginners, although in my personal opinion, the Raspberry Pi 3 is still the best option because of the more mature community and the improved operating system.
