Review on Treedix 3.5-inch Color TFT LCD Display Module with 320 x 480 Resolution for Arduino UNO R3, Mega2560, and Due Compatibility by Charles Parente

The display looks nice, fits snugly on the mega board but blocks other pins. With rectangular pins you should be able to bypass this if needed or use cables to connect instead. Install the MCUFRIEND_kbv library to use this board. There is a github repository with source code and instructions, prenticedavid/MCUFRIEND_kbv. You'll also need to install the Adafruit GFX library - install the BusIO dependency when prompted. check if everything works. Uses 29,724 bytes. I haven't tested anything that uses the microSD slot, but it should be easy to find.
