Waveshare ESP32-S3 1.75inch AMOLED Round Touch Display Development Board, 32-bit LX7 Dual-core, 466×466, QSPI, Dual Digital Microphones Array, ESP32 with Display, with GPS

Key Features

• High-Performance MCU Board: The ESP32-S3-Touch-AMOLED-1.75 is powered by the ESP32-S3R8 Xtensa 32-bit LX7 dual-core processor, running at up to 240MHz. It integrates a range of features like a 1.75-inch AMOLED capacitive touch display, a 6-axis IMU (accelerometer and gyroscope), RTC chip, and more for quick development and product integration.
• Connectivity and Memory: It supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with an onboard antenna. The board is equipped with 512KB SRAM, 384KB ROM, 8MB PSRAM, and an external 16MB Flash memory for smooth performance and ample storage.
• Touch Display and Audio: The onboard 1.75-inch AMOLED display offers a 466×466 resolution and 16.7 million colors, with QSPI and I2C communication for efficient IO resource use. Dual digital microphones provide audio features such as noise reduction and echo cancellation for voice recognition applications.
• Motion and Power Management: Integrated 6-axis IMU (accelerometer and gyroscope) detects motion gestures and step counting. The AXP2101 power management IC ensures optimized battery life, with a rechargeable 3.7V Lithium battery and low-power operation, powered by a lithium battery with uninterrupted supply via the RTC chip.
• Expandable and Customizable: The board includes a 3 × GPIO and 1 × UART header, reserved pads for I2C and expanded IO interfaces, and an onboard TF card slot for extended storage and fast data transfer. This allows for easy peripheral connection and debugging, making it highly adaptable for various applications.
