ESP32 S3 Arduino LVGL Four Inch Display

Excellent value for money and, more importantly, there are several projects out there that use it. esp home takes you all of 10 minutes to get it installed with no coding and you can have a panel for home assistant.

Item delivered very quickly and well package. i was able to create a great multi timer project with this screen with the help of claudeai and it works exactly as i need, would be great for busy kitchens. the screen is a good resolution and is a very compact unit. it runs the timer application for 12 hours on one charge of the 2350mah battery from an old phone. i even made a small stand for the unit. i would certainly buy again if i can think of another project.

Even if there is a speaker terminal, this product does not produce sound immediately.

This is the ESP32-4848S040 4-inch product. The screen, touch, and Wi-Fi are working, but those who want to use the built-in speaker output need to check.

I connected a 4Ω 3W speaker to the Speak terminal, but there was no sound.

Even when I switched to a different speaker and used USB power, the same issue persisted, and not only the voice files on the SD card but also the test sounds created directly without files did not play.

Upon checking the board photos, the R21, R22, and R23 for internal amplifier connections were empty, and 0Ω resistors were installed on R25, R26, and R27.

The technical documentation for the same model states that to use the built-in speakers, this resistor arrangement needs to be changed to connect the audio signal to the amplifier.

Currently, I have given up using the speaker without any soldering modifications. I did not check whether the output was normal after the modification. If the speaker requires separate fine soldering work for use, I think it should be clearly stated on the sales page.

I got in love with screens. used an already build project from github and it worked like a charm. the touch is also very nice. will get some more in the futur for sure.

Great, would definitely come again.

Very good screen, works perfectly. I really like that it is carefully and safely packaged. Functionality and quality are 10/10. The only downside is that you have to tap the printer handle, as there are no handles available for purchase for EU cans.

Arrived to the uk within 3 days. flashed with espcontrol and now i can add home assistant devices to the screen without any coding knowledge. superb!

Works amazing in home assistant. was super easy to setup using esphome / espcontrol

Fast shipping and works great!

Picked this up to test its use as a ha room climate/lights control panel. Installed espcontrol and instantly have a super customisable and very functional controller. Screen animation is slow but with minimal use of animation, it is just perfect.
Now to work out how i permanently power it in place of my existing wall switch.

Very nice display! can be used with lvgl and eez studio! only 3 i/o available but works very fine a lot of memory and good velocity

Great! I was able to redo the interface for my Intex spa.

It works well and is well packaged, as shown in the photos.

This is not an ESP32 processor! !! This is a processor I am not familiar with. I bought the device as an ESP32.
The device starts up, but the sensor is very slow to respond. It's like a phone from the past, 20 years ago. Perhaps I would leave the device and study it, but I don't like the fact of being deceived. I am returning the product.

Chiaro, Marco — let's keep the focus where it *should* be: screen and speed come first, BLE just as a functional note. Here is a much more balanced version.

I am using this ESP32‑S3 LVGL development board as the control interface for my camper's electrical system, and it has been excellent so far.

The **4.0'' 480×480 capacitive touch display** is truly impressive: bright, sharp, and extremely responsive. Combined with the smooth performance of LVGL, the entire UI feels fast and modern.



I am also using **BLE scanning** to retrieve data from my devices (MPPT, DC‑DC, battery monitor, etc.). ), and the board handles it without any issues — a nice bonus for integrating everything into one dashboard.



Overall, the build quality, speed, and display clarity make this a fantastic choice for custom control panels or monitoring systems. Highly recommended.

I bought it, it came damaged in the bottom corner, I want to return it since it is broken and they force you to pay the shipping costs. Aliexpress has been managing customer service poorly lately.

ESP32-S3 Arduino LVGL WIFI and Bluetooth development board 4.0 inch 480 * 480 smart display capacitive touch without bottom shel

Works as expected with hacs beta, fast. A bit tricky to wall mount, the plastic bracket holds the pcb in the frame. Ordering a second one now.

Very nice little screen and esp combo, makes a perfect currently playing track display. Display is bright and updates quickly

The screen stopped functioning after about a week. Loaded lvgl config into it through home assistant and it was working fine one day and then the next had horizontal lines going through the display. No config change could fix it. Disappointed because it seemed like a nice piece of hardware.

Works great for me. Got it working with lvgl 9.4, lovyangfx, platformio, esp core v3.3.4, eez studio, etc, by porting the existing demos to the latest versions of everything with claude. See my github, "joevial", for more info. Yes this is a real espressif esp32-s3 chip, it's just not inside an espressif-made package. The package includes the chip, the crystal oscillator, the psram chip, all under a metal tin. Someone else made the metal tin, that's all.
