ChatGPT

ESP32 LCD Touch Display

ESP32 LCD Touch Display adalah kombinasi mikrokontroler ESP32 dengan layar LCD (TFT) yang dilengkapi panel sentuh. Kombinasi ini sering digunakan untuk HMI, dashboard IoT, panel kontrol, dan perangkat pintar berbasis Wi-Fi.


🔧 Tentang ESP32

  • Mikrokontroler dengan Wi-Fi & Bluetooth bawaan
  • Dual-core (pada sebagian besar varian)
  • Banyak GPIO dan periferal
  • Efisien untuk proyek IoT & embedded

🖥️ Jenis LCD yang Umum Digunakan

  • ST7789 – Resolusi 240×240 / 240×320 (SPI)
  • ILI9488 – Resolusi 320×480 (SPI / Parallel)

LCD berbasis SPI lebih sederhana wiring-nya, sedangkan parallel lebih cepat untuk animasi berat.
