Introduction
T-Display AMOLED Plus is a high-integration development board based on the ESP32-S3 microcontroller, designed for multifunctionality and high performance. It features 16MB Flash and 8MB PSRAM, enabling the execution of complex applications. The board includes a 1.25-inch AMOLED display with touch functionality.
It comes with a built-in PMU (Power Management Unit) and RTC (Real-Time Clock), along with VBUS power management, optimizing it for low-power applications. For expansion, it offers STEMMA QT/Qwiic dual interfaces, supporting rapid sensor connections, SD card storage, and provides ample GPIO, ADC channels, and UART interfaces for peripheral integration.
Additionally, the board features BOOT mode switching and a reset circuit for easier development and debugging. This product is ideal for smart wearables, IoT terminals, and other scenarios requiring interactive displays and multi-sensor integration.
