Hi,
For my first Arduino project requiring a screen, I choose for simplicity to work with " 3.5inch Touch LCD Shield for Arduino". the projects works just fine but I need to get the screen placed away from the Arduino Mega itself, I thought about wiring the pin header connections between the Arduino and the Shield but probably there is cleaner solution.
I am not away of the HW protocol/interface used in this screen, are there other screens that can be used with cable connections? in case these have different controller other than the "ILI9486" I will have to re-write part of my code right ?
Please post a link to the actual screen that you have bought. e.g. Ebay sale page.
God invented Shields so that you could plug them into your Arduino.
3.5 inch screens have a larger footprint than a Uno / Zero. And about the same as Mega2560 / Due.

I need to get it about 25-50cm away (10-20 inches), I am integration my circuit in a design which is not ready at this moment.
This solution should be good enough if I get all my soldering clean.
Also, I am preparing a prototype for a product, when mass production phase comes I think that this will not be a feasible thing to do for each unit.
For mass production I assume you'd be going through a stage of pcb design etc anyway. You can decide on interconnects at that stage. For the prototype some wires should be ok.
Hi Frezek,
David's link only supplies a front picture.
I would be great to have a picture of the back of your screen where the pins are. Pins count!

I don't have this hardware. But I guess that the library will perform 100%.
Yes, Panels with 8080-16 interface are cheaper than SPI panels. Hence Waveshare's parallel screen with Shift Register feature. The performance is obviously not as good as a genuine SPI panel.
The OP can copy the "design" and schematic and use it for his custom product.
I don't like the idea of extended wires whether it is for SPI or parallel. However SPI has less wires to pick up noise / reflections.
In my message I was referring to this one.
I constructed benches for the ESP32WROOM-32: one that accommodates SPI TFTs and one that accommodates parallel TFTs, that is Arduino shields. The TFTs perform great with Bodmer's TFT_eSPI library, I especially like the Arduino shield with their fast parallel interface. posted:ESP32-WROOM-32 and Uno-shield parallel TFT displays – thesolaruniverse
I took the parallel TFT off the ESP32 bench and re-connectedit through 30 cm Dupont wires. This appeared to work fine with my upcoming Muybridge's Elephant animation, approx. 8 fps , 220x128 C-formatted bitmaps - fortunately, elephants move s l o w l y). Conclusion: one can at least an ESP32 connect through 30 cm wires with a parallel display. See photo 1
Then I took off the SPI TFT from its ESP32 bench and re-connected it with the 30 cm Dupont wires. I got the elephant working, but the SPI TFT did not really like it (initially no image; flicker). this TFt is also a ILI9341 320x480 display. This is all AliExpress stuff so measure out the quality. onclusion: one can at least an ESP32 connect through 30 cm wires with a SPI display - remains tricky. See photo2
