Description

Waveshare ESP32-S3-Touch-LCD-1.69 is a compact ESP32-S3 development board with a 1.69inch capacitive touch LCD, built for portable UI devices, smart control panels, and embedded display projects. It integrates the ESP32-S3R8 wireless MCU, 8MB PSRAM, 16MB Flash, QMI8658 6-axis IMU, RTC, and a 3.7V lithium battery charge / discharge circuit, making it a practical platform when you need a small display, touch interaction, wireless connectivity, and battery-ready hardware on one board.

Features

• ESP32-S3R8 onboard: Xtensa 32-bit LX7 dual-core processor with up to 240MHz frequency, paired with 8MB PSRAM for more capable graphics and embedded workflows.
• 1.69inch capacitive touch display: 240280 resolution, 262K colors, and capacitive touch control for clear, responsive UI interactions.
• 16MB Flash storage: Provides useful room for firmware, assets, and local data in display-oriented ESP32-S3 projects.
• Battery-friendly platform: Includes a 3.7V lithium battery connector and charging support for portable devices.
• Motion and timekeeping: Combines a QMI8658 6-axis IMU with an onboard PCF85063 RTC.
• Compact HMI hardware: Includes buzzer, buttons, USB Type-C, and exposed GPIO for extending the board into custom products.

Specifications

Applications

• Portable HMI devices: A good fit for rechargeable mini dashboards, handheld instruments, and touch-based status panels.
