    Both screens work very well and the package is exceptional value for money. Arrived on time and well packaged Took me awhile to get them working. A few tips which may help? Download and use the MCUFRIEND libraries. MCUFRIEND_kbv-2.9.9-Release 2.8" screen (blue PCB) : Identifier and driver 0x6809. Touch screen pins XP=7,XM=A1,YP=A2,YM=6 My calibration int TS_LEFT=932,TS_RT=164,TS_TOP=156,TS_BOT=922 2.4" screen (red PCB): Identifier 0x0000. You need to force the identifier/ID to be 0x9341 On mine the text came out mirrored. Need to edit the MCUFRIEND_kbv.cpp file Find case 0x9341 (line2570 for me). In line 2571 add INVERT_GS. See line below lcd_capable = AUTO_READINC | MIPI_DCS_REV1 | MV_AXIS | INVERT_GS | READ_24BITS; Save the modified cpp file Use PORTRAIT_REV to get correct screen orientation (printed icons at the bottom) My Colours were in RGB (565) format and need changing to BGR e.g BLUE changes from 001F to F100. (5 most sig bits need to be least sig and visa versa. Middle 6 bits are OK). There may be a better way of doing this ? Touch screen pins XP=6,XM=A2,YP=A1,YM=7 My touch screen calibration: TS_LEFT=934,TS_RT=178,TS_TOP=212,TS_BOT=941; The touch screen mapping will probably need changing to get the correct directions of movement. Where required swap x and y and or left and right values.

    Delivery time as quoted. Packaging very ordinary, but items are undamaged. Using the displays is not easy as the software provided in the downloads does not work. However the AdaFruit TFTLCD library works well, with some changes to the pinouts. The 2.8" display appears to include connectors for the Arduino pins that are not accessible when the shield is installed - if so that is a nice feature, but they aren't mentioned in the documentation. The UNO has thruholes for headers (supplied) which could be used to get access to the GPIO pins concealed by the display. A nice feature, but it is actually easier to use a stackable prototype board between the UNO and the shield. The 2.4" display shows noise bars down one third of the display and is not usable. Would be good value for money if both displays worked.

    Good product. Unfortunatelly some of the programs dont perform as expected, only the color test works. The red one came broken at the middle, seems transport issue.

    messing around with the uno and the 2.4 screen just ran some examples from library spfd5804 from the arduino site and the calibration is off someone has made change to the pin settings on 2.4

    Prodotto ottimo, verificato il funzionamento e la qualità, tutto perfetto. Imballo ottimo e nessun danno al contenuto. I test sono stati eseguiti usufruendo delle indicazioni fornite dal venditore. Verificato anche con test del touch screen, esito nell'utlima immagine.

    Excellent value for the price. Both screens and UNO appear to be well made and are in good working order. Note that both displays include dual logic level converters, so these displays are fully 5v compatible. Delivered ahead of estimate. Packaging excellent (cardboard box in plastic envelope). Items are undamaged. Using the displays is not easy as the software provided in the downloads does not work. However the AdaFruit TFTLCD library works well, with some changes to the pinouts. Others have had success with the MCUFriend library. The 2.8" display includes 18-pin DIL header thruholes: the pinout is not documented but does include the serial port. The UNO has thruholes for headers (supplied) which could be used to get access to the GPIO pins concealed by the display. A nice feature, but it is actually easier to use a stackable prototype board between the UNO and the shield.

    Item arrived intact, and all functions as it should. No dead pixels or anything. Great deal for what you get!

    Haven't programmed yet. Intend to use for digital temp controller for kiln. Touch input screen will be very helpful for programming heating/cooling cycles.

    All 3 pieces work very well, the X and Y points are reversed from standard and the direction on one display is reversed from the other.... no problem but pay attention when trying to get examples to work. A poorly documented pin sharing issue with setting pinmode xm and xp to output after TSPoint is required. This is no fault of the product just very hard to discover why user written code fails .

    Muito bem embalado em uma caixinha com todas as peças, cada um dos displays e a placa UNO vem embaladas em sacos antiestáticos.
