LILYGO T-Display S3 AMOLED 1.64

Overview

The LILYGO T-Display S3 AMOLED 1.64 is a development board centered on the ESP32-S3R8 microcontroller paired with a stunning 1.64-inch AMOLED display. The ICNA3311 (CO5300) display driver delivers a 280×456 pixel resolution over a QSPI bus, offering deep blacks and vibrant colors characteristic of AMOLED panels — ideal for wearable UIs, dashboards, and interactive prototypes.

Capacitive touch is handled by the FT3168 controller over I2C, enabling touch-based navigation and gesture recognition. The SY6970 power management IC provides battery charging capability, supporting portable operation from a LiPo battery. The board enters a very low deep sleep current of approximately 254.5µA, making it suitable for battery-sensitive applications.

With 16MB of flash and 8MB of Octal SPI PSRAM, the T-Display S3 AMOLED 1.64 has generous resources for sophisticated graphics applications, web servers, and complex firmware. USB CDC on boot enables easy firmware updates without a separate programmer.

Firmware Compatibility

The board is compatible with Arduino IDE, PlatformIO, and ESP-IDF. The GitHub repository at https://github.com/Xinyuan-LilyGO/T-Display-AMOLED-1.64 includes examples for display rendering using LVGL and other graphics libraries, touch handling, and battery management.

Flashing Guide

1. Install the ESP32 board package in Arduino IDE 2.x or configure PlatformIO.
2. Connect via USB-C; USB CDC on boot enables automatic detection.
3. Select ESP32-S3 Dev Module with 16MB flash and 8MB OPI PSRAM settings.
4. If not auto-detected, hold BOOT and press RESET to enter download mode.
5. Upload your sketch or use idf.py flash with ESP-IDF.
