1.85-inch Round Knob Screen

1.85‑inch Round Knob Screen – A Compact Yet Powerful Smart Interaction Solution

The 1.85‑inch Round Knob Screen is a compact smart interaction solution that combines high‑quality display, responsive touch control, and rotary knob operation. It features a 360×360 IPS fully laminated capacitive touch screen that delivers crisp and vivid images, while supporting both touch sliding and knob rotation for intuitive and smooth interaction. At its core is the Espressif ESP32‑S3R8 dual‑core processor running at up to 240 MHz, providing ample computing power and fast response. Built‑in dual‑band Wi‑Fi and Bluetooth 5.0 (BLE) ensure stable and reliable wireless connectivity; onboard rich expansion interfaces and compatibility with mainstream development environments make it flexible for use in smart appliances, portable devices, industrial tools, and more.

In terms of functionality, it integrates nearly all multimedia peripherals: audio playback and MJPEG video decoding are supported, along with an adjustable RGB ambient light, speaker, and vibration motor. Out of the box, it comes pre‑loaded with multiple practical applications – it can serve as a secondary PC monitor (compatible with AIDA64 monitoring), a digital photo frame, an audio spectrum analyzer, and even emulate a keyboard and mouse, offering plenty of room for creative expansion. The unit features an integrated design for plug‑and‑play use, requiring no external complex circuitry. We also provide full‑process custom development services – from hardware adaptation to UI design – offering a one‑stop solution for your smart device human‑machine interaction needs.
