Waveshare ESP32-S3 1.46inch Round Display Development Board, 412×412 with widened protective cover glass

The Waveshare ESP32-S3 Touch LCD 1.46 development board is a compact embedded display platform based on the ESP32-S3 dual-core processor. It features a 1.46-inch IPS round touchscreen with 412×412 resolution, designed for smooth graphical user interfaces using frameworks such as LVGL. The board supports 2.4GHz WiFi and Bluetooth 5 (BLE), and includes onboard flash and PSRAM for embedded applications. It provides lithium battery charging support via a 3.7V Li-ion MX1.25 connector and exposes GPIO interfaces for external peripherals. The ESP32-S3 architecture allows expansion for features such as I2S audio (microphone/speaker), external IMU sensors, RTC modules, and TF card storage depending on the specific hardware variant or add-on modules. This makes it suitable for IoT dashboards, wearable prototypes, and interactive embedded UI systems.
