Funciona perfecto a 3.3v

I saw reports that you needed to be careful with not using the MISO signal from the LCD because it got held even if the LCD was not selected. It isn't needed for LCD so I just left it disconnected on the LCD port. But when I tried to get the SD card to work, it wouldn't and I traced it down to the MISO signal on the SD port apparently not getting to the SD card holder at all!. After I added a wire to connect MISO the SD worked.Not only that, but I found that the resistive touch sensor had irregularities such that the centre columns and row responses were very non-linear and required a custom calibration even after the usual calibration of the corners.I do not recommend this product. You can make it work if you try hard, but there are better choices.

Two versions ship The most up to date version , do not connect SDO (MISO pin next to the LED pin) or touch does not work, even though that pin is a display pin. Old version works even if SDO is connected, but should also work without it. The new version (The one I got anyway) has yellow plastic on the soldered pins. Some microcontrollers require a 10K resistor connected to 3.3 V on from each of the cs pins you have connected to the microcontroller as CS pins. (One for CS display and one for CS touch). Runs great on my teensy 4.1. (I used the ILI9488_t3 libray which only works on teensy boards, but have also gotten it to run with other boards using other libraries) Enjoy!!!

The part arrived same day from Amazon. The display is nice with the 3.5 inch display. There are plenty of example programs for the ILI9488 controller it uses in the teensyduino arduino IDE libraries. The touch interface uses an XPT2046 controller. A couple of items I had using the display. The "DO_MISO" pin on the TFT section is not needed to display information. If connected to the SPI bus it, stopped the MISO line, so I do not connect it. It will keep other devices on the SPI bus which need MISO, such as the touch interface and SD card interface, from working if it is connected. The example programs I have used, connected to teensyduino 3.6 or 4.1 development boards ( 3. 3 volt boards ), some using the TFT screen, touchscreen and SD card at the same time, have worked OK.
