Hosyond 4.0 Inches 480x320 TFT Touch Screen LCD Display Module SPI ST7796S Driver for Arduino R3/Mega2560

Very nice display! Worked great, and with AI, I was totally able to use this and learn. I liked it so well, I bought another. Use AI, know which driver the display needs, and start creating! And I'm a newbie with non-oled displays. But treat the display nicely! I cracked my first one by dropping it, so it was totally my fault.

The product works really well when using the hardware interface. However, when using it with an Arduino board it uses up all but one PWM pin and all the SPI pins. I was hoping to dedicate the display to one Arduino and use the SPI bus to link several units and display data from them. Not possible. I'll have to find another solution.

If you wire it up correctly, this thing flies. It handled my specific need with ease. The touch functions work well. Fair notice, you need an Arduino Due in order to get enough speed from your micro controller to drive this high color unit. I like the fact that we can wire directly to the pins and we don’t have to use a shield. That makes it perfect for my application.

Very good supplier and excellent product

Price is alright but field of view is terrible
