What is a Rotary Screen? A rotary screen is an intelligent interactive device that combines a rotary knob with a display. The knob allows users to rotate and press to control different functions, while the screen displays real-time information, menus, and system status, offering intuitive human-machine interaction. ESP32-S3 1.28 Inch Rotary Display Overview The ESP32-S3 1.28 inch rotary display is a smart HMI display module built around a high-performance ESP32-S3 dual-core chip. With a maximum clock frequency of 240MHz, it is capable of handling complex tasks such as UI rendering, wireless communication, and real-time control. This ESP32 display supports capacitive touch input and rotary encoder operation. The knob supports clockwise rotation, counterclockwise rotation, and full press actions, providing smooth tactile feedback and multiple interaction methods for modern embedded interfaces. Wireless Connectivity & Expansion With integrated 2.4G WiFi and BLE low-power Bluetooth, this ESP32 HMI display easily connects to the Internet and other devices, making it suitable for IoT projects, smart home controllers, industrial control panels, and portable devices. The module features a 5V charging interface for power supply and program burning, and includes UART, I2C, and FPC expansion interfaces, offering flexibility for further hardware integration and product development. Designed for Developers and Product Makers The ambient light design adds a modern and interactive feel to the device, while the low power design makes it suitable for energy-efficient and battery-powered applications.
