Waveshare ESP32-S3-Touch-LCD-1.46 Round Display Dev Board with Cover Glass

Description

Waveshare ESP32-S3-Touch-LCD-1.46B is the protective cover glass version of Waveshare’s 1.46inch round touch display development board. It combines the ESP32-S3R8 platform, a 412412 round LCD, touch control, 8MB PSRAM, 16MB Flash, QMI8658 6-axis IMU, PCF85063 RTC, TF card slot, microphone, speaker, and battery-ready power design in one compact board. This makes it a strong fit for voice-enabled HMI, smart control panels, portable dashboards, and round LVGL / ESP32-S3 GUI projects where the added cover glass is useful for protection and a cleaner finished look.

Features

• ESP32-S3R8 onboard: Xtensa 32-bit LX7 dual-core processor up to 240MHz with Wi-Fi and Bluetooth 5 LE support.
• 1.46inch round touch display: 412412 resolution with 16.7 million colors, suitable for more refined circular UI layouts.
• With protective cover glass: This SKU corresponds to the 1.46B version, which adds the official protective cover glass.
• Audio input and output hardware: Onboard microphone, speaker, amplifier, and PCM5101 audio decoder for audio-driven interaction projects.
• Motion, RTC, and storage: Includes QMI8658 IMU, PCF85063 RTC, and TF card support for richer embedded applications.
• Battery-ready design: Supports a 3.7V MX1.25 lithium battery, battery recharge management, and RTC battery expansion.

Specifications

Applications

• Voice-capable round HMI: The display plus microphone and speaker path make it suitable for speech-oriented UI experiments and smart controls.
• Portable dashboards and wearables: Useful for battery-powered circular interfaces with motion sensing and RTC support.
• Smart home and desktop control panels: A good fit for room controllers, touch interfaces, and connected visual control nodes.
• Multimedia ESP32-S3 projects: The audio hardware and TF card slot help with media playback, prompts, and richer user interaction.
• LVGL and GUI prototyping: The round 412412 screen, PSRAM, and Flash configuration support more advanced graphical layouts.

FAQ

Is this the version with protective cover glass?

Yes. This SKU corresponds to the ESP32-S3-Touch-LCD-1.46B version with protective cover glass.

What is the difference between 1.46, 1.46B, and 1.46C?

The 1.46 version is the standard board without cover glass, 1.46B adds protective cover glass, and 1.46C uses a widened protective cover glass version.

Why is this board stronger than a basic round display board?

Besides the round touch screen, it also includes audio input/output hardware, IMU, RTC, TF card, and battery support, which makes it much more capable for interactive ESP32-S3 projects.
