DIYmalls 2,8' Zoll ESP32 Display Kapazitiver Touchscreen ESP-32 Bildschirm TFT LCD Modul ESP-WROOM-32 Entwicklungsboard ST7789 240x320 JC2432W328C für Arduino IDE

Was a gift for my techie husband and when he powered it on the screen was completely glitchy. Like they resold a busted product return. He tried to repair it endlessly until we finally gave up. Skip this one- not worth it. Better to go to a physical store where you can inspect the product or a store you know you can trust at least. Zero functionality out of this product. Impossible to use.

I was at first disappointed that there was not an accessible user manual or program samples at the DIYMall web site. I contacted DIYMall who was very responsive to my request in obtaining the manual and sample programs to get me started in developing my projects. I am very pleased. The board is of very good quality and well worth it price. It comes with a nice store box and connector cables. Very fast and responsive touch screen.

This is what is commonly known as a "CYD" or "Cheap Yellow Display"; however it appears to have been upgraded with capacitive touch (over resistive) and USB-C (over Micro) from the examples I've seen demonstrated on YouTube.If you're just looking for a CYD and already know what you're in for, this hardware seems to be decent; go for it. Otherwise, read on...For those unaware, this is a pre-built ESP32 (Wifi/BT) + MicroSD + Touch Display combo, making for a self-contained HMI. The idea is you can make control panels for homes, robots, music players, etc.It has plenty of IO connectors (and supplied plugs), an RGB LED for status indication and LDR for ambient light sensing. It also comes with a pleasing reusable plastic storage case for the accessories.The display itself is sharp enough, not particularly bright or colourful; but decent. As far as I can tell touch input is reasonably reliable, but the preinstalled demo was not fully functional, or at least, many of the interactions didn't work as expected.Getting alternative software onto this beyond a basic 'blink' demo was a challenge, as the 'classic' CYD tutorials I'd planned to use weren't compatible with this altered version. I ended up messaging the seller as described in the listing, and to their credit, they quickly sent a link to a download with a large number of demos and supporting software inside. It was only flagged by four lesser-known AV engines on VirusTotal, so (probably) fine.However this is where the jank comes in.To date I've used Arduino (and clones), Teensy, Seeduino XIAO, Espruino, ESP32, STM32, and many other boards besides. All have varying degrees of difficulty/complexity in terms of getting software compiled and flashed, with ESP32/STM32 in my opinion being the most consistently problematic.The documentation PDF included in the download is certainly thorough; if a little hard to follow in places. I think they really put a lot of effort into writing this up, which is why I haven't marked the product down; but it could be considerably better.There's a lot of moving files around between libraries and the demo files; basically making a mess of your Arduino libraries directory for this one board.Compiling the demo mentioned in the documentation has proven to be painful due to a seemingly endless array of bad file paths, and bad (outdated?) sample code.After a few hours of trying to get the 'full' demo working, I've run out of time and patience with it. Simple demos work fine, but don't use the features of the board.The ESP32 is a good chip with plenty of capabilities. The hardware as I say seems to be great; but I haven't got a project in mind for this yet that justifies the attention it needs to be programmed and developed for.I've recently used the TFT_eSPI library they're using with a Waveshare round LCD, so I know it works just fine; if being a little awkward to write UIs with.I'd say this is very much NOT for newcomers to the world of microcontrollers. Start with a genuine Arduino, Seeeduino XIAO, Teensy or similar for a better experience, then add a separate display module and learn how they interact without the steep learning curve of a device like this.

Das Modul "DIYmalls 2.8 Inch ESP32 Display Capacitive Touchscreen ESP-32 Screen TFT LCD Module ESP-WROOM-32 Development Board ST7789 240x320 JC2432W328C for Arduino IDE " wird in einem antistatik Beutel geliefert.Im Lieferumfang enthalten ist die Platine, ein paar Jumperkabel.Es funktioniert alles wie beschrieben, einfach und zufriendestellend.

Wäre ein super Gerät, wenn nicht das Display bei Bewegung Flickern würde. Somit fast unbrauchbar.

Die Produktverpackung besteht aus einer Kartonschachtel, das Board wurde zusätzlich noch in einer antistatischen Tüte + Kunststoffbox verpackt, so dass es besser gegen antistatische Aufladungen geschützt ist.Inhalt: 2.8" ESP32 Display, 2x 1,25 mm 2-poliges Kabel, 2x 1,25 mm 4-poliger Dupont-Buchse und 2x 1,25 mm 4-poliger Dupont-Stecker.Eine Anleitung liegt nicht dabei, wenn man den Verkäufer anschreibt, bekommt man eine Anleitung auf Englisch zugeschickt.Geflashed wird das Board über eine USB-C Schnittstelle, der USB zu Serial Chip befindet sich schon auf der Platine.Die Verarbeitung und Qualität sehen allgemein sehr gut aus. Die Lötstelen sind sauber und gerade, sogar die Beschriftung lässt sich gut ablesen.Auf dem Board befinden sich noch eine BOOT und eine RESET Taste, ein Anschluss für den 4 Pin Dupont Kabel, 3x IO-Anschlüsse, Speak Anschluss, ein Bat Anschluss, ein Bat switch, sowie ein Micro-SD Kartenslot.Es sind für alle Anschlüsse auch die passenden Kabel dabei, bis auf das USB.Kabel.Das Display hat einen kapazitiven Touchscreen, das heißt, dass man es auch mit dem Finger/Haut bedienen kann.Das Testprogramm, was schon auf dem Board gespielt wurde, läuft mit dem Touchscreen auch relativ schnell und flüssig, mit dem resistiven Touchscreen hat es deutlich mehr gehackt.Die Außenmaße sind ca.: 86mm (L) x 50mm (B) x 10mm (H).Preis/Leistung von ca. 25€ ist für dieses ESP32 mit Display und Touchscreen sowie mit vielen weiteren Anschlussmöglichkeiten absolut in Ordnung.Wer schon mal mit Arduino gearbeitet hat und sich ein wenig mit Elektronik auskennt, sollte mit dem Board gut klarkommen, für komplette Anfänger wird es vermutlich nicht so leicht werden, da sollte man sich zuerst einmal mit ein paar kleinen Sensoren beschäftigenIch werde auch nochmal versuchen, das Board in mein Smarthome System einzubringen, um mir ein paar Informationen anzeigen zu lassen.

This was the perfect solution for a product a customer needed me to build for him. Works great, easy to program with the Arduino IDE...what's not to like?

This is a nice combo motherboard (JC2432W328C) combining both a screen a few aux connectors for things like batteries and buttons, additional access of an SDcard for storage and of course the ESP32. This is the WROOM model. The screen is the ST7789.I couldn’t get the web address working that was included on the box, but searching the motherboard model number did bring up some data sheets, user manual, example code etc.Just remember to use the esp32 by espressif when using the arduino IDE and you’ll be away.Board does come with some demo code already running on it, showing touch screen buttons, animations, it’s colour range etc. It’s worth having a good poke around at them before venturing on so you know what you can expect from it.The screen is nice and bright, colourful but quite limited in resolution. However it is mounted proud of the PCB, and the PCB has holes for screws, so you can easily include it in a 3D print or cut an hole in a project box for a touch screen interface for your projects.
