LilyGo T-Encoder Pro ESP32-S3 with Touch

The T-Encoder Plus combines an ESP32-S3 microcontroller with a 1.2-inch AMOLED round display and a rotary encoder for versatile control tasks. The 390 × 390 pixel display offers a clear representation and responds precisely to touches thanks to the capacitive touch sensor. The rotary encoder supports left and right rotation as well as a push button, enabling intuitive operation. An integrated buzzer provides audio signals, and a vibration motor offers haptic feedback. Two Qwiic connectors allow easy expansion with I2C sensors and actuators, while the RTC RTC8563 chip ensures accurate time tracking. With 16 MB flash and 8 MB PSRAM, this board offers ample memory for demanding applications and supports 2.4 GHz Wi-Fi and Bluetooth 5 for wireless communication. The SH8601A display driver and CHSC5816 touch controller ensure stable screen and touch functions. The compact housing measures 45 × 45 × 32.3 mm at only 40 g, making it ideal for portable projects. With its black design and two 4-pin Qwiic ports, the T-Encoder Plus is suitable for applications such as macro pads, smart rotary knobs, volume controllers, or interactive IoT controllers.
