Web installer for the ESP32 Cheap Yellow Display (CYD 2432S028)
⚠️ Panel support: currently only the ST7789 display variant is
supported - ILI9341 support is coming soon. Rough guide: newer boards
with two USB ports (Micro-USB + USB-C) are usually ST7789,
older single Micro-USB boards are often the unsupported ILI9341. Sure
test: if the screen stays white after flashing (while Wi-Fi still
works), your board has the ILI9341 panel.
