AZDelivery 3 x AZ-Touch MOD DIY Smart Home Kit: 2.8 inch TFT LCD Touchscreen Module XPT2046, PCB ILI9341, with Wall-Mount Casing, for ESP8266 and ESP32 compatible with Arduino Including E-Book!

Great little touchscreen. Wanted to build a touch screen smart bulb switch panel for all my smart bulbs in my house, interfacing through homeassistant. It took lots of Googling plus a really helpful review on here showing correct pin out configurations. I built this using the esp32 nodemcu module from AZ delivery. Here is my config for esphome, I hope it helps someone: esphome: name: tscontrol esp32: board: esp32dev framework: type: arduino # Enable logging logger: # Enable Home Assistant API api: ota: password: #### wifi: ssid: !secret wifi_ssid password: !secret wifi_password manual_ip: static_ip: ###.###.###.### subnet: 255.255.255.0 dns1: ###.###.###.### #dns2: #.#.#.# gateway: ###.###.###.### # Enable fallback hotspot (captive portal) in case wifi connection fails ap: ssid: ###### password: ######## captive_portal: spi: clk_pin: GPIO18 mosi_pin: GPIO23 miso_pin: GPIO19 xpt2046: id: touchscreen cs_pin: GPIO14 irq_pin: GPIO27 update_interval: 50ms report_interval: 1s threshold: 400 dimension_x: 240 dimension_y: 320 calibration_x_min: 3860 calibration_x_max: 280 calibration_y_min: 340 calibration_y_max: 3860 swap_x_y: False output: # backlight - platform: ledc pin: 15 id: gpio_15_backlight_pwm inverted: true light: # backlight for HA - platform: monochromatic output: gpio_15_backlight_pwm name: "ILI9341 Display Backlight" id: back_light restore_mode: ALWAYS_OFF text_sensor: - platform: homeassistant id: mblightgroup entity_id: light.bedside_lights - platform: homeassistant id: emmabedside entity_id: light.smart_lighting_tunable_white_and_color_3 - platform: homeassistant id: jonbedside entity_id: light.smart_lighting_tunable_white_and_color_2_2 - platform: homeassistant id: kitchenlights entity_id: light.kitchen_lights - platform: homeassistant id: kitchenlight1 entity_id: light.smart_bulb_2 - platform: homeassistant id: kitchenlight2 entity_id: light.smart_bulb_3 - platform: homeassistant id: kitchenlight3 entity_id: light.smart_bulb_4 - platform: homeassistant id: livingroomlights entity_id: light.living_room_lights - platform: homeassistant id: livingroomlight1 entity_id: light.mk_smart_led_bulb_rgbpro - platform: homeassistant id: livingroomlight2 entity_id: light.mk_smart_led_bulb_rgbpro_2 - platform: homeassistant id: porchlight entity_id: light.smart_bulb - platform: homeassistant id: toiletlight entity_id: light.smart_lighting_tunable_white_and_color - platform: homeassistant id: landinglight entity_id: light.smart_lighting_tunable_white_and_color_3_2 - platform: homeassistant id: hallandlandinglights entity_id: light.hall_and_landing_lights - platform: homeassistant id: halllight entity_id: light.smart_lighting_tunable_white_and_color_4 - platform: homeassistant id: girlslight entity_id: light.smart_lighting_tunable_white_and_color_2 display: - platform: ili9341 model: TFT 2.4 id: touch_display cs_pin: GPIO5 dc_pin: GPIO4 reset_pin: GPIO22 rotation: 180 pages: - id: page1 lambda: |- it.fill(Color::WHITE);

This has great potential if only the manuals were available in English (The old version in English is for a very different board) and the ESP32 libraries worked so don't expect an easy ride. I started by asking AZ for the latest manual which they did promptly mail me but it was not in English. With about an hours work converting the PDF to English using google translate and then copy and pasting in the pictures that were lost I ended up with a document that was vaguely of some use. I will be using the ESP32 Dev C module which with my electronics engineering hat on is plugged into the board such that the receiving socket is on the other side (IE push module pins through board into the sockets on the opposite side which with an English manual would be very difficult to figure out, let alone one in German. Now I am into heavy library debugging as the HTTP libraries for the ESP32 clearly have issues despite compiling ok. In summary, a bit of kit with great potential but don't expect an easy ride to get any value out of it so I would leave it to electronics engineers with serious software debugging skills. As the say in England, a fantastic sailing ship ruined because of a halfpenny of tar missing! Meanwhile I will keep debugging the software and I may make an update if I get it working... Update: After correctly installing all the correct libraries in the Arduino IDE as system libs and compiling the example "codelock" sample on their website and making a few debugging code changes it all worked well so very happy in the end (see attached demo) but it was hard work getting there and not a job for a novice coder.

This is a great bit of kit, just need to add an ESP32, you need to solder the sockets for the touch screen and either an ESP32 or a ESP8266. You need to use the right sockets/holes for your ESP and the touch screen. Note the ESP mounts on the opposite side of the board to the touch screen. I couldn't create the manual in English on the AZ website so took a bit of Googling to get the layout drawing which makes things much clearer. The standard screen setup for ESPhome is wrong for this unit you need to use:- spi: clk_pin: GPIO18 mosi_pin: GPIO23 miso_pin: GPIO19 xpt2046: id: touchscreen cs_pin: GPIO14 irq_pin: GPIO27 update_interval: 50ms report_interval: 1s threshold: 400 dimension_x: 240 dimension_y: 320 calibration_x_min: 3860 calibration_x_max: 280 calibration_y_min: 340 calibration_y_max: 3860 swap_x_y: False I have mine displaying values from other Home Assistant devices, have a PIR page that pops up automatically when motion detected, and have control of a light using a touch button on the screen. My only regret is not going for the 2.8" screen

The promised documentation STILL doesn't exist. Fortunately, if you're prepared to do some serious legwork, you can Indiana Jones your way to a murky backwater of the manufacturer's website and, if you hand over your email addrrssy, get a terse PDF detailing a kinda similar item for a different MCU. From that point, experience and confidence might see you through. Me, I'm taking it verrry slow! In conclusion, IT'S DISGRACEFUL THAT THIS SELLER CONTINUES TO BLATANTLY LIE, AND JUST AS DISGRACEFUL THAT AMAZON TOLERATES IT. EDIT: After a fortnight's fruitless toil, I'm declaring this item a BRICK. I've been sold something that SIMPLY DOES NOT WORK IN ANY WAY WHATSOEVER. THE ALLEGED EBOOK DOES NOT EXIST. THE SELLER IS SURELY AWARE OF BOTH THESE FACTS. THE SELLER STILL TAKES MONEY FOR THE ITEM. There's a word for that...

Looked perfect for what I want - very disappointed to find (pre-fitted) surface mount capacitor loose in the box and damage to PCB tracks where it was fitted

Prodotto molto ben fatto, corredato di distanziatore e viti per il fissaggio del display anche quest'ultimo a corredo, il tutto in un contenitore plastico riutilizzabile come portaminuterie. Unica nota negativa è che per progetti diversi da quelli per cui è stato concepito ho dovuto modificare alcuni dei collegamenti esistenti sul PCB, inoltre trovo scomodo il montaggio del WEMOS D1 proprio sotto al display, ma nel complesso sono molto soddisfatto. Suggerisco al venditore di offrire in vendita anche il solo guscio ad un prezzo ragionevole in modo da poterlo usare anche per progetti diversi che usano altri tipi di dispositivi.

Antes de mais, um obrigado à AZ-Delivery pela rapidez na entrega. Chegou tudo muito bem acondicionado. Fisicamente tanto a caixa como a board é de muita qualidade, onde permite a integração com o display (2.8") ILI9143. Visualmente tem um acabamento profissional. Pontos negativos que deu para identificar algumas situações. Infelizmente o kit não permite a utilização do I2C, pois uma das linhas, está a ser utilizada pelo reset do display e a outra pelo Led do LCD. Outro ponto negativo é a "tomada" onde entram os pinos do ESP32. Um mau contacto e o display não passa do branco. Como tenho o projeto, basicamente a identificar/medir certos parâmetros em casa e a enviar via Wi-Fi para o ThingSpeak de 30 em 30 segundos, sobre (24h/24h), com apresentação gráfica e base de dados, estava em falta uma caixa de proteção, e este kit veio mesmo a calhar. Resumindo, fazendo umas pequenas alterações nas pistas da board, lá consegui integrar a comunicação I2C. (seria bem mais fácil se fosse entregue com o kit um diagrama elétrico da board). A informação disponibilizada é de uma placa diferente. De salientar também a versatilidade da biblioteca TFT_eSPI. Tem a possibilidade de ser alterada (User_Setup.h). Boa informação e com exemplos extraordinários. Para o meu projeto visitei os seguintes sites: A nível de software um obrigado ao Rui Santos (https://randomnerdtutorials.com/), e ao Fernando K (https://www.fernandok.com/). A nível de hardware um obrigado a AZ-Delivery (https://www.az-delivery.de). Bom hardware a preços muito acessíveis.

I can actually run everything via power from the USB port on my ESP8266 D1 Mini but have done no measurement or long time test. Someone also mentioned that the two I2C pins where occupied by the display pins but you can change it like this: Wire.begin([SDA], [SCL]);
