AZDelivery 2.4 inch TFT LCD Touch Screen Module XPT2046 PCB ILI9341 240x320 Pixels 8-bit SPI Serial Port Display 300mA 5V 3.3V compatible with Arduino Including E-Book! (Pack of 3)

The media could not be loaded. I purchased the 2.4inch TFT touchscreen to use with a Raspberry PI for a mini arcade machine build I'l planning, but for the purpose of this review, all testing was done on an Elegoo Uno R3.Without the usual excellent AZ Delivery downloadable PDF quick start guide avaiable yet, I was still able to set up and test the screen in around 20 minutes.Set Up - Really easy. Make sure the pins from the screen line up correctly and press on like any other shield. Flip the screen over and look at the 3v3 and 5v pins to make sure they go into the correct holes on the Uno. Basically, it installs from the furthest hole back on the Uno.Testing - There's loads of information and data available on the ILI9314 but until the quick start guide is available from AZ, I used the examples from ElectroPeak which utilise the Adafruit Touchscreen libraries. These allowed me to quickly test the touch screen with feedback to the serial monitor and to display images and text to the screen directly.As you can see from the posted video, the screen is nice and bright (even though I've left the protective screen on!) and seems to refresh quick enough.Quite looking forward to installing this one on my Raspberry Pi :)

The media could not be loaded. UPDATED 11/12/2020DISCLOSURE: this product was supplied by AZ Delivery free of charge but without obligation. All opinion expressed here is my own.Raspberry Pi have HATs (Hardware Attached on Top) and Arduinos have shields, but they are broadly the same thing - a device intended to attach directly to the 2.54mm pitch sockets fitted to these development kits. The Pi and the Arduino, while broadly similar (both are ARM-based computers at heart), fit into very different markets. The Pi is much faster but also requires some sort of operating system to do anything useful whereas the Arduino (based on the ATMegas) and that makes it suitable for low-performance, low-power tasks.In many cases, the Arduino and its copies are driving little more than a simple 2-4 line LCD display or at best, an OLED display. OLEDs are low-power but they remain (as of this writing) expensive, usually quite small, and have fairly short working life: particularly in the blue. Full colour OLED are the rarity for now although they do exist and even appear in televisions now.LCDs however, being a much more mature and popular technology have a much longer working life and lower cost at the expense of greater power consumption from the necessary back lighting and more limited viewing angle.This particular shield comes by way of AZ Delivery, a German supplier and the quality is, as you might expect. The excellent design drops into the Arduino Uno with very little effort (I used an Elegoo clone, available from Amazon with the full-sized, socketed ATMega).And that’s when it dawned on me for the first time that (a) I didn’t have any instructions - AZ-Delivery produces its documentation via PDF but the English translations are slow and (b) this shield takes a LOT of the available I/O lines. How many? Almost all of them - in fact the only ones remaining are the i2C (SDA and SCK) and IOREF (+5v). Not even a ground is free. Strictly this isn’t true as there are ground pins available at the two ICSP programming headers o the UNO. More of this in a moment though.SPI isn’t available as that’s being used for the SD reader and it wired directly the board’s hardware interface. An essential piece of forethought as it means that that existing SD read/write libraries should work without modification.At its simplest, this shield will find use as part of a small digital picture frame project - particularly married to a 3D printed case and with the low cost of both parts, it’s a good starter project for anyone who has outgrown making an LED blink or some of the simpler Arduino demonstrations and something that is useful - if small.Naturally, without a display library to make it work, this is shield is going to look like a rather expensive piece of glass. Fortunately, such a library exists in the form of David Prentice’s MCUFriend - which can be directly installed from your Arduino library manager. I was able to get the examples going with no more effort than loading them to the board. This even included using the resistive touch screen and displaying some fairly complex graphics.ERRATA: An earlier version of this review suggested that the i2C bus was available (from Rev. 3 onwards) but in fact these pins are already in use and only duplicated which lead to my error. However, if you don't want (or need) to use the SPI interface to the microSD card reader it should possible to remove four pins on the header (carefully!) from 10 through to 13 without losing too much physical strength leaving room for some (albeit limited) communication with the outside world either through four digital pins or the hardware SPI interface.The Good:CheapBright and colourfulResistive touchscreens are robust and reliableEasy hardware SPI access to the SD reader/writerThe Bad:Lack of English language instructions. A deal-breaker for many.Restricts access to SPI even if you don’t use the SD cardResistive touchscreens usually need a stylus (supplied)Blocks most of the usable connection on the UNO limiting what you can do with it.Slow.UPDATE: After some experimentation, my student and I were able to create a really neat and fully functional thermohygrometer (temperature and humidity) based on the Elegoo Uno with a single extra component, the ubiquitous DHT22 (both available from Amazon Prime at pocket-money prices). The final result, called "HotStuff" is now described in detail on Instructables and pictured here in both the faux LCD mode an clock version which is under development. With just three wires to connect (plus power) this is an ideal project for a young person to make and it's something that won't just go sit in a drawer as it's actually useful in multiple scenariosA 3d-printed case is all that's needed to finish this project off and create something quite special that looks almost like a commercial offering costing... well, about the same really, but you'll have made this yourself and that's something money just can't buy! The video doesn't show the current version but will give some idea of what it looks like when it's running (the flashing symbol indicates that the air is too damp and could cause mould growth).

Purchased via Amazon – ordered 20-Sept and delivered next day (SKU MAR2406)PACKAGINGSupplied in strong, good quality AZ_Delivery carton. The display itself and associated stylus are inside a sealed bag with the pins protected by pieces of expanded foam. This sealed bag is itself inside a bubble wrap pocket. Well packed and no reference made about anti-static handling requirements.PRODUCT INSPECTIONScreen has protective film in place. All header pins look well soldered and are straight. Header pin identification is clear although there is no specific documentation as to how to connect.SET-UP & TEST Using MEGA (8-bit mode)I had to hunt around for the libraries but once that was sorted it worked out great.Goto LCDWiki, select 2.4inch Arduino product – you can see this has the same MAR2406 code as on the AZ packaging label. Download the package files, unzip and move the LCDWIKI_GUI , LCDWIKI_KBV and the TOUCHSCREEN Libraries to the library folder.I used a MEGA so have not tested the SD Card in that set-up. However, running all the other example files and then modifying the switch test program to allow 3 leds to be switched on and off was straight forward and worked successfully. Easy to use shield – just plug in- with an excellent, clear and bright screen. Using with the MEGA rather than an UNO gives so many pins left for a project.

I'm not sure if the display actually works as the 'included e-book' which requires your to register to download it doesn't currently exist in English. What you get is '2,4 TFT LCD Touch Display - ENGLISH ENG - eBook is under construction.png'. Might exist in German.The product description indicates the module uses an SPFD5408, but the packaging for the modules indicates an ILI9341. Time to figure out which it really is and see if I can make it work.

Används som skärm på Arduino Uno Rev3 och fungerar precis som förväntat. Använder MCUFRIEND biblioteket och kom igång ganska snabbt efter några exempel. Hade önskat att man kunde dimma eller stänga av skärmen via kod, men det är tyvärr inte möjligt. Får se hur länge den håller om den är igång 12h per dygn. Testade Touch-funktionen via något av exemplen som följde med MCUFRIEND och det tycktes fungera helt ok. Skärmen är fullt läsbar för mitt användningsområde och bra pris.

Componente perfetto per l'Arduino. AZ-Delivery, una garanzia

vlot geinstalleerd, libs vlot gevonden

El módulo LCD TFT  funciona perfectamente, con arduino Uno y Mega. El módulo tiene una buena calidad, tanto en acabado como en las soldaduras.Tiene una buena retro-luminosidad para poder utilizarlo en condiciones de luz alta. Tanto los colores como la nitidez del texto son bastante buenos.Utiliza el  controlador ILI9341  con lo que facilita la utilización de las librerías existentes. La información de los pines viene serigrafiada en la placa de forma bastante legible.Utiliza casi todos los pines del Arduino Uno para el funcionamiento de la pantalla y las correspondientes para el control de la SDCard. Y por la configuración del shield no se pueden acceder a los pines libres. Para utilizar más pines e implementar su funcionalidad la probé en Arduino MEGA y funcionó perfectamente.La función de pantalla táctil funciona muy bien con ayuda del puntero incluido en la caja. Aunque me costó un poco su configuración para que funcionara correctamente.Una vez insertada en la placa arduino, se puede acceder fácilmente al lector de tarjetas SdCard , que funciona perfectamente con las librerías SD.Una función que no he podido implementar es la utilización con módulos ESPxx para su utilización en Internet de las cosas IOT y la utilización con la plataforma sensate.io.Tal vez se deba a mi falta de información, ya que no he podido descargarme a día de hoy el eBook en ningún idioma, ya que pone que está en preparación.Por lo general considero un módulo muy bueno ya que incluye la pantalla táctil y el lector de tarjetas SDCard por un precio asequible y fácil de conectar y utilizar con arduino, para una gran variedad de proyectos.
