I didn't have any way to play the CD that came with enclosed instructions on how to use this, but a good YouTube tutorial did the trick. Elegoo provides modified Adafruit_TFTLCD and Adafruit_GFX libraries designed to be compatible with the Arduino Mega, which they also sell separately. These modified libraries aren't available on the IDE, so I had to download them and manually insert them into the IDE's library folder. After that it should work really great once you boot up an example. Really good brightness, although, (as any LCD screen would, so I expected this), you can't achieve true blacks with this screen. That doesn't matter at all though. The "touchscreen" part of this works pretty neatly with the examples provided, although sometimes you might have to apply a little bit more pressure than you're used to with the capacitive touchscreens that iPhones and other mobile devices feature. Overall this is a fantastic device and absolutely worth buying. I might buy another one in the future if I need it. Review: Fantastic little display, looks great and works as expected, amazing price - Fantastic little display. Looks great, works as expected and is really an amazing price. Additionally, Elegoo has great test apps included that you can download. The sample apps include fantastic examples that you can extend for your own use. There are some really interesting examples in there which show you how to deal with the touch screen and how to rotate the display and everything. Really great. I received the display yesterday and started wiring it up to my Arduino Nano -- a bit more of a challenge than using it with an Arduino Uno since the Nano is so small and doesn't have the headers just to plug the screen directly in. All Problems Were My Own I struggled with it for quite a while because I couldn't get it to display anything. I opened up Arduino Serial Monitor and could see good messages appearing telling me it was initializing but all I could see was a backlit white screen. I wasn't sure what was wrong so I went back and checked all my lines with a continuity tester (multimeter setting) and finally I discovered I had two of the data lines flipped with each other. I switched them over and everything worked perfectly. It looks great and works great as you can see in the picture. I'v also uploaded a picture of the back of the screen to show the pinouts. One challenge for doing the wiring myself was also that some of those pins are not used and you have to get everything aligned properly. If you get this set up properly it will work. Again, this is a fantastic little display, especially for the price. ## Features - Tutorial in cd, better price, better service.

But the libraries included do not support that. I was able to modify the simplest example to make it work with the R4, but it ended up being a lot slower than using the LCD on an UNO R3, even though the R4 micro controller is a lot faster. The difference is that with the R3 the data is loaded as a byte while the R4 needs to be a bit at the time. I was unable to locate function for writing a byte. I'm sure it can be done, but I have not found it. Since the LCD worked better with an UNO R3 board, I decided it wasn't worth the effort to make it work with the R4 board. Using the LCD with an UNO R3 board, it works well. Especially considering the low cost. The display is bright, with nice colors. The library uses 5 bits per color, but I don't think there are that many levels available. The touch screen works OK. But you do need to use the included stylus. Using a finger doesn't work as well. One thing to keep in mind is that most pins are used, so only the I2C interface is available. You will need to solder the wires directly to the board to get access to it. The included examples were helpful. ## 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? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/27529836-elegoo-uno-r3-2-8-inches-tft-touch-screen-sd](https://www.desertcart.tw/products/27529836-elegoo-uno-r3-2-8-inches-tft-touch-screen-sd) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-16*
