Tutorial Included If you can not use a CD, you can also download the electronic version of the tutorial from the official website elegoo.com/pages/download ..................FAQ.................. Q1: How to power it? A1: This screen can be powered directly by UNO motherboard, the cable used is USB -A TO B port cable, no additional power supply is required. Please note: If you want to use this screen with Arduino R4, please download driver on ELEGOO Wiki. Q2: Why the 2.8-inch TFT screen does not work? A2: Please use Example01-Simple test to check the screen first. This code file does not use any library file. If this code file can make the screen work properly, there may be a problem with the library file. If the screen still does not work, it may be defective. Please send us a picture showing the connection between the 2.8-inch screen and the controller board, and we will help you solve the problem. Q3: The touch function of the 2.8-inch TFT screen does not work? A3: Please try to upload the following code to the control board. drive.google.com/file/d/1wps9b6sMZNwhEfTe6SEEvCfTFbGid5lL/view?usp=share_link When you touch the screen, it will display the X-axis, Y-axis and pressure value of the touch on the screen. The X-axis value is close to 1000 to 100 from left to right. The Y-axis value is close to 100 to 1000 from top to bottom. Just feel free to let us know if there is still a problem. Q4: How to turn off the backlight of the 2.8 inch TFT screen? A4: The backlight circuit is directly connected to the 5V and GND pins on the PCB board. The backlight can only be turned off by turning off the power. Review: Great little board - also the missing manual. - I'm happy with this module, it comes with a micro-SD card reader, touch layer, and TFT Liquid Crystal Display all in one. I didn't expect much to work properly given this board is 4 times cheaper than the well known touchscreen display on the market. But I've been happily surprised. Everything works smoothly, and the touchscreen is accurate in reading points across the entire surface. (There is NO calibration issue as you control the offset in code yourself) The card - being a shield - means you can just line up the pins on the board to the mount holes on the Arduino, and the card pushes firmly into place. The mini CD that comes with the device (see below for a link) has all you need to get it running, the drivers, libraries, and example code. Once I'd placed the libraries into the Arduino system, I opened the 6 examples and they all ran without issue. It was great! The build quality is excellent - the surface mount chips are all soldered well, the display is mounted cleanly on the PCB. You even get a little plastic stylus for the capacitive touchscreen. Warning! You might need to power your Arduino board along with the USB power. I found my little laptop couldn't power the bright white screen LED's, RGB screen, and Arduino all at the same time. The Arduino would repeatedly "unplug", and then "replug". Once I'd supplied extra power through the Arduino jack plug, it stayed connected. No more brown-outs. I might just buy another one to build a permanent project. -------------------------------- As you NEED to know what the electronic details are, I've included the CD contents on my site: Untamed Dot Co Dot Uk The link is right at the top, and includes the PDF's of the datasheets and libraries and examples. The missing manual. (At least on the product page) Key features: Driver chip : LGDP4535 (The CD also includes data sheet for the ILI9341) Level converter : 5v to 3.3v Screen resolution : 320 x 240 Screen colour: RGB, 65,000 colour. Uses 8 bit parallel bus. Includes Micro SD card holder. Includes Arduino libraries and examples. Review: Excellent product, particularly for the price! - Using mine with a Uno as a UART to touch display interface. I have a mega that controls my home heating, and through a ~10m long UART connection, I can control and display via the touch screen. The library I found had the incorrect touch pins configured, so if you have touch problems (no detection) double check your #defines. I was also unable to fully configure the touch calibration using the example code (right edge was not detecting), but through trial and error got the correct calibration values. A few suggestions/tips. Although the SD card works, using the sd lib requires a lot of SRAM (512 bytes are required for sd card block writes), so thats 25-30% of the uno's memory space right there. So for my own scenario, I instead wrote code that reads in from the UART buffer to directly write to the display, parsing for commands to set text colour, position etc. By deleting functions/code not required for my exact tft screen, I freed up alot of space. If you are using the screen for something simple like me, its possible to use an uno, however, anything more complex and it does not have the memory to really do anything useful (and only has the UART pins free), so I would recommend a mega. I was also worried that I would REQUIRE the pen for any useful touch input, but the screen is extremely responsive to touch, more than I thought possible with a resistive panel. Edit: I purchased a second one, both going great left on 24/7. ## Features - Warning:Not suitable for children under 3 years.

This is due to different hardware configurations. **Q: Will it work with raspberry pi?** A: Yes. I bought this for my hubby who uses it all the time for his Raspberry Pi projects. πŸ‘ **Q: Can this screen control LEDs via the touchscreen when combined with an arduino?** A: Alex. Yes you can. You can turn LEDs on or off depending on what's on screen. **Q: Where are the arduino uno drivers? they are not available on website. only raspberry pi instructions are there.** A: Hi Will, Thanks for your question.

All the demos just worked in my clone UNO. The resistive screen is a little hit and miss, it tends to need a prolonged press rather than a dab. If you watch the data from polling the position, you'll see a lot of null results and a report approx 1 in 10 to 1 in 20 times which is likely what causes the sluggish feel. The screen also isn't perfectly supported so you can feel it flex when pressing in some areas. A little better with the stylus, but does work with a fat finger. The colours and graduations are good and the provided library does everything I've asked. I'm data logging temperatures so having the ability to create a touch based menu and create charts with a few line drawing commands is very useful. The only downside is that with a UNO this screen uses almost all the pins. A5 is free which you can use in digital or analogue mode and digital pins 0 and 1 can theoretically be used but as these are shared with the USB serial interface to flash and debug your results may vary. Using a Mega eliminates this problem as there are lots of other interfaces, however you then need to manually rewire the SD card interface as the Mega pinout is different. The official screen uses a different interface which leaves a lot of pins free but is slower to refresh. Overall a good additional if you can live with the limitations (Uno) or spend a little more on a Mega. ## Frequently Bought Together - ELEGOO UNO R3 2.8 Inches TFT Touch Screen with SD Card Socket w/All Technical Data in CD for Arduino UNO R3 - ELEGOO UNO R3 Board for Arduino with USB Cable(Arduino-Compatible) More Faster In Transfer Rates And Better At Storage And Operation - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/47870400-elegoo-uno-touch-screen](https://www.desertcart.com.ar/products/47870400-elegoo-uno-touch-screen) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-26*
