Introduction
T-Display AMOLED Plus is a high-integration development board based on the ESP32-S3 microcontroller, designed for versatility and high performance. It features 16MB of Flash and 8MB of PSRAM, enabling support for complex applications. The board comes with a 1.25-inch AMOLED display with touch functionality, offering vibrant visuals and interactive control.
It includes an onboard PMU (Power Management Unit) and RTC (Real-Time Clock), with VBUS power management to optimize low-power design. For expansion, the board provides dual STEMMA QT/Qwiic connectors for rapid sensor integration, supports SD card storage, and offers a wide range of GPIOs, ADC channels, and UART interfaces for peripheral connections.
Additionally, it integrates BOOT mode switching and a reset circuit, simplifying development and debugging. This board is ideal for scenarios requiring interactive displays and multi-sensor integration, such as smart wearables and IoT terminals.
