Introduction
The T-Display-S3-AMOLED-1.43 is an intelligent display development board integrating the high-performance ESP32-S3 dual-core Wi-Fi/Bluetooth SoC, designed specifically for IoT and interactive applications. At its core is a 1.43-inch AMOLED display with a high resolution of 466×466 pixels, supporting touch input and featuring a built-in PCF8563 real-time clock (RTC) for precise time management.
The board is equipped with 16MB of FLASH storage and 8MB of Octal SPI PSRAM, and supports Micro SD card expansion for additional storage needs. It also integrates battery voltage detection via ADC and a USB Type-C power interface, making it convenient for portable and mobile use cases.
Offering a range of expansion interfaces including SPI, I2C, and GPIO, the board is compatible with touchscreen interaction and SD card data operations. It's well-suited for applications such as smart wearables, industrial control systems, and embedded GUI development, combining high performance with low power consumption.
