About This Project
The Cheap Yellow Display (ESP32-2432S028R) bundles an ESP32, a 2.8in 320x240 ILI9341 touchscreen, an SD slot, an RGB LED and a speaker header on one cheap board. This repo by Brian Lough collects working pin definitions, library setup (TFT_eSPI, LVGL), and dozens of community example projects from weather apps to game emulators. It is the best starting point for anyone who wants a touchscreen ESP32 gadget without wiring a display.
