LILYGO T-Encoder Pro

Overview

The T-Encoder Pro is a compact and capable ESP32-S3 development board combining a physical rotary encoder input with a bright 1.2-inch AMOLED display. The display uses the SH8601A-W14-T06 driver via QSPI bus at 390x390 pixel resolution, delivering sharp and vibrant visuals for menus, instrument panels, and interactive UIs.

Powered by the ESP32-S3 R8 with 16MB flash and 8MB PSRAM, the board has ample resources for complex UI logic and wireless communication. The onboard buzzer on PIN IO17 enables audio feedback, while dual Qwiic 4-pin connectors simplify integration with sensors and peripherals using the I2C-based Qwiic/STEMMA QT ecosystem.

Three color variants are available: Orange (K249-02, $31.74), Black (K249, $31.05), and Yellow (K249-01, $31.05). Silicone cases are also sold separately for $1.30. The T-Encoder Pro is ideal for building smart home control panels, audio equipment controllers, or any application requiring a premium rotary input with visual feedback.

Firmware Compatibility

The T-Encoder Pro supports Arduino IDE and ESP-IDF. The LILYGO AMOLED display driver library handles the SH8601A display. Example firmware is available in the Xinyuan-LilyGO GitHub organization under the T-Encoder-Pro repository.
