LilyGo AMOLED Plus T-Display S3 ESP32-S3 with 1.9 Inch Display

The LilyGo AMOLED Plus T-Display S3 is a compact development module with a powerful ESP32-S3 microcontroller and an integrated high-resolution AMOLED display. The 1.9-inch screen offers brilliant color reproduction, high contrast, and excellent readability even in daylight. An ESP32-S3R8 with MB PSRAM and 16 MB flash is used as the processing unit, ideal for graphics-intensive applications. The product features a USB-C interface for programming and power supply. A JST connector is available for mobile use, allowing a LiPo battery to be operated and charged directly. The reset and user buttons on the back facilitate interaction in everyday use and during development. Numerous GPIOs are accessible on the side via soldering strips. Two 14-pin and two 2-pin headers are included and enable direct soldering if needed. The integrated RGB LED allows for simple status displays to be implemented directly. The compact format makes the product ideal for portable controls, sensor displays, or IoT user interfaces.
