Embedded electronics specialist LILYGO has launched a brand new compact touch-screen improvement board constructed across the Espressif ESP32-S3: the two.41″ full-color AMOLED LILYGO T4 S3.
The brand new improvement board, dropped at our consideration by CNX Software program, makes use of Espressif’s ESP32-S3 system-on-chip as its base — that means there is a dual-core 32-bit Tensilica Xtensa LX7 microcontroller operating at as much as 240MHz and with vector directions for higher-performance on-device machine studying and synthetic intelligence (ML and AI) workloads, plus 8MB of off-chip pseudo-static RAM (PSRAM).
Elsewhere on the board is 16MB of flash storage with microSD growth, a 3D antenna with IPEX connector for an exterior antenna — utilizing a single connection for each the on-board Wi-Fi 4 and Bluetooth 5.0 Low Vitality (BLE) radios — and a USB Kind-C port for each energy and programming.

The spotlight of the board’s design, although, is the full-color show which dominates the entrance of the system. Constructed utilizing active-matrix natural light-emitting diode (AMOLED) expertise, the show has a 600×450 decision with a claimed 800cd/m² brightness. It is absolutely touch-sensitive, LILYGO has confirmed, and talks to the host microcontroller over a quad-SPI bus.
The gadget consists of two Qwiic ports for exterior {hardware}, a 30-pin 1.27mm-pitch header exposing accessible general-purpose enter/output (GPIO) and energy pins, and a JST-GH connector for an optionally available battery. Formally, the board helps improvement in PlatformIO, the Arduino IDE, and MicroPython — however unofficially needs to be suitable with something that may run on the Espressif ESP32-S3, as long as you will discover driver libraries for the show.
The LILYGO T4 S3 is now accessible on the corporate’s official retailer, priced at $56.89.
