What customers say
This Adafruit ILI9341 display is highly valued for its seamless integration and excellent quality. Users consistently praise the vibrant colors and sharp resolution provided by the ILI9341 controller, noting the display exceeds expectations for its category. The inclusion of a resistive touchscreen and MicroSD socket adds significant utility, simplifying project setups. The primary driver of positive feedback is Adafruit's comprehensive libraries, which greatly reduce the difficulty of programming the display. While some users mention minor calibration needs for the touchscreen or challenges reaching peak SPI refresh rates, the overall consensus remains strongly positive due to the board's feature density and reliability. It is a highly recommended component for makers.
Know before you buy
Yes, this breakout board is compatible with a wide range of Arduino boards, including the Mega2560 and Leonardo. Because it uses standard SPI communication, it can also be adapted for use with many other microcontrollers.
This module uses a resistive touchscreen, which means it responds to pressure. You can use a plastic stylus, a fingernail, or even a gloved finger to interact with the interface.
Absolutely. The onboard MicroSD socket is designed to store bitmap images or other data, which you can then load and display on the screen using your microcontroller.
The display features a 4-LED backlight that is powered by the board. While it is always on by default, you can control the brightness by connecting the backlight pin to a PWM-capable pin on your microcontroller.
The display uses the SPI interface, which typically requires four pins for the display data, plus additional pins for the touchscreen and MicroSD card functionality. You will need to ensure your microcontroller has enough available digital I/O pins to support these connections.
