## Description

## Overview

The LILYGO T-Encoder Pro is a smart rotary control knob built around the ESP32-S3R8 microcontroller, featuring a 1.2-inch round AMOLED display with 390×390 resolution driven by the SH8601A chip over QSPI. The knob supports bidirectional rotation with a clickable center button, CHSC5816 capacitive touch sensing, a built-in buzzer for audio feedback, and a vibration motor for haptic response. With 16MB flash, 8MB PSRAM, 2.4GHz WiFi, and Bluetooth 5 LE, the T-Encoder Pro is well-suited for wireless smart home controls, media volume knobs, and custom UI input devices. Dual Qwiic 4-pin connectors allow easy expansion with I2C sensors and peripherals. Compatible with Arduino IDE and ESP-IDF with LVGL graphics framework support.
