Waveshare ESP32-S3 1.85-Inch Round LCD Development Board

Description

The Waveshare ESP32-S3 Development Board is engineered for rapid prototyping of Human-Machine Interface (HMI) and smart audio devices. Its core is the Espressif ESP32-S3 microcontroller, featuring a dual-core LX7 CPU capable of 240MHz operation, paired with substantial 16MB Flash and 8MB PSRAM to handle memory-intensive graphical interfaces and machine learning models.

Wireless connectivity is provided by integrated 2.4GHz Wi-Fi and Bluetooth 5.0 Low Energy radios with an onboard antenna, enabling IoT device networking and BLE peripheral control. The board’s standout feature is the 1.85-inch, 360×360 resolution round LCD, driven via QSPI for smooth graphics rendering with frameworks like LVGL. A suite of onboard peripherals, including an audio codec, microphone, real-time clock, and battery charging circuit, makes it a turnkey solution for creating interactive smart speaker boxes, portable diagnostic tools, and industrial control panels.
