LILYGO’s Upgraded T-Display-S3 AMOLED for $25.68 USD

The T-Display-S3 AMOLED is a development board and is an updated version of the T-Display-S3 and has the first combination of an ESP32-S3 with an AMOLED display. The previous LCD display has been replaced with an AMOLED one, which results in an improved color display. In addition, it now features a QSPI interface instead of an SPI interface, which results in increased speed. The onboard antenna has been replaced with a 3D antenna, which results in an enhanced WiFi and Bluetooth experience.

The datasheets, schematics, and basic instructions to get started with the Arduino IDE, PlatformIO, or the ESP-IDF may all be found on GitHub.


The T-Display-S3 AMOLED is quite comparable to the T-Display-S3 and the T-Display-S3 Touch; the primary distinctions between these three displays are detailed in the table that follows.


It is compatible with any microcontroller that supports SPI using the SPI interface. A module is a practical option for portable applications because it has a built-in battery management mechanism. It is perfect for wearable and Internet of Things projects because of its small size and low power consumption.
