This is a nice fast display once you find the right library for it. While the touch screen can use the UTouch library, the only one I could find that worked with the display was a modified AdaFruit (the mcufriend_kbv) library. If running on a Mega 2560, the shield is necessary. This is a 3.3v display and has more pins than the Mega. When I need another 3.2" display, I will definitely be buying another one of these.
I gave the communication a 5 star rating only because it's required. I never had a need to communicate with the seller.
I got this because I know a professor who loves line follow bots. I got it as a gift so I cant review the kit itself. It does come well packaged and looks nice. The only small gripe is that the schematic and instructions are given to you as a hyper link on a card. That said its not really a big deal. It shipped fast and was well protected. I would recommend it to others.
Display works great. I have not tested touch and SD yet. It was very hard to figure out which driver in UTFT should I use to communicate with display. At first, I also forgot to connect unused RD signal to logical 1 which made it even harder to make it work. Finally ILI9325D_8 worked for me. I was unable to find suitable 16 bit interface driver or switch it to 16 bit (there is not a switch mentioned in the documentation).
This is a quality relay board with all of the little details included, like optocouplers to protect the GPIO pins on my Pi. I only gave the documentation 3 stars because I did not see (or need) extra docuemntation (though I would have liked to see the circuit protection details mentioned in the description - I gleamed that detail from a clode ciew of the product images).
