T-Display-S3-Pro-LR1121

Introduction

T-Display S3 AMOLED Plus is a high-integration development board based on the ESP32-S3 microcontroller, designed for multifunctional and high-performance applications. It features 16MB Flash and 8MB PSRAM, enabling support for complex programs.

The board includes a 1.25-inch AMOLED touchscreen display and integrates PMU (Power Management Unit) and RTC (Real-Time Clock) for optimized low-power operation, with VBUS power management support.

For expansion, it offers dual STEMMA QT/Qwiic connectors for quick sensor integration, SD card storage support, and a rich set of GPIOs, ADC channels, and UART interfaces for peripheral connection.

Additionally, it includes onboard BOOT mode switching and a reset circuit, simplifying development and debugging.

This board is ideal for applications like wearable devices and IoT terminals requiring interactive display and multi-sensor integration.
