LILYGO T-Display S3 AMOLED Plus

Overview

The LILYGO T-Display S3 AMOLED Plus is a development board featuring the ESP32-S3R8 paired with a 1.91-inch RM67162 AMOLED display. The display delivers a 240×536 pixel resolution over an SPI interface with a 19.8×44.2mm active area, offering the deep blacks and high contrast ratios characteristic of AMOLED technology in a tall, narrow form factor suitable for watch-face or status bar UIs.

The board includes capacitive touch for interactive applications, an RTC (real-time clock) for timekeeping without network synchronization, a TF/SD card slot for local data storage, and a battery holder for untethered operation. A metal shielding cover reduces RF interference, and an external FPC antenna improves WiFi and Bluetooth range. GPIO female pins provide an expansion interface for additional peripherals.

The T-Display S3 AMOLED Plus is compatible with Arduino, PlatformIO, ESP-IDF, and MicroPython. It is positioned as an upgrade over the standard T-Display S3 AMOLED, offering a taller display with a more portrait-oriented form factor.

Firmware Compatibility

Compatible with Arduino IDE, PlatformIO, ESP-IDF, and MicroPython. LILYGO's GitHub organization provides display driver examples for the RM67162 using LovyanGFX and LVGL. The wiki at wiki.lilygo.cc has additional documentation and pinout information.
