📺 2.2 Inch ILI9341 SPI TFT LCD Display with SD Card Slot: Ideal for Arduino and Raspberry Pi Projects Review

Bitsnbyte's YouTube channel has instructions for a network of resistors to set the voltage of Arduino signals to 3.3V (not Arduino's VCC) for a similar Oled to lower the screen. I read the top comment that the voltage (vcc) should be 3.3V and when I tested it it was the first. It works well. Can buy more

It was a nightmare from day one. I used a 1kΩ resistor for all lines except power and ground, but sometimes it works and sometimes it doesn't. Much luck.

Display is fast enough for use with oscilloscopes. Some colors are quite inaccurate, especially the extremes, which can be adjusted by programming the gamma/display curve. The color issue could also be due to the use of the Teensy Optimized Display Library. Do yourself a favor and use a potentiometer or PWM on the LED backlight. Works on 5V board with resistors/linear converters, works better on 3.3V board without them. I'm using a 10k pullup resistor on the CS pin with Teensy 3.5/4.1 boards…

I broke mine trying to use 5V for Vin. 5V only works for backlight. I was disappointed to learn that the SD card slot, despite being installed on the same board, has separate pins. In operation, this is no different than a fully separate SD card reader. Unsatisfied.
