Waveshare ESP32-S3 1.8-Inch Knob Display Development Board w/ CNC Case

Description

This development board integrates a high-performance ESP32-S3 alongside an ESP32 microcontroller, creating a versatile platform for AIoT and human-machine interface (HMI) projects. The primary ESP32-S3 handles the 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE + Classic) stack, while the dual-core architecture manages the high-resolution IPS display and capacitive touch interface efficiently. The inclusion of a precision rotary encoder knob adds a tactile control dimension, ideal for parameter adjustment, menu navigation, or media playback.

Power management is designed for portable use, supporting a 3.7V 800mAh lithium battery via a built-in charging circuit, enabling operation in standalone kiosks or smart control panels. The board’s extensive peripheral set—including I2S audio output, a MEMS microphone, and a microSD card slot—allows developers to create multimedia applications, voice interfaces, or data-logging systems without external components. The robust CNC-machined aluminum case not only protects the electronics but also gives the device a professional, end-product ready appearance suitable for prototyping and low-volume production.
