Adafruit 2.8” TFT Touch Shield v2

Overview

The Adafruit 2.8” TFT Touch Shield v2 with a resolution of 320x240 pixels, is based on the ILI9341 controller. This shield comes with a resistive (STMPE610 controller) or capacitive (FT6206 controller) touchscreen. While the Zephyr RTOS supports display output to these screens, it currently does not support touchscreen input. More information about the shield can be found at the Adafruit 2.8” TFT Touch Shield v2 website [1].
