Elecrow CrowPanel 1.28inch-HMI ESP32 Rotary Display 240*240 IPS Round Touch Knob Screen
The rotary screen is an intelligent interactive device that usually consists of a circular knob and a display. The knob can be rotated to control various functions, while the display is used to display relevant information.
ESP32 Display - 1.28 inch rotary screen, uses high-performance ESP32-S3 chip, equipped with 32-bit dual-core chip. The maximum clock frequency reaches 240MHz, with strong performance and the ability to handle complex tasks.
Supports 2.4G WiFi and BLE low-power Bluetooth, to achieve reliable wireless communication, easily connect to the Internet, suitable for smart home, industrial control, portable devices and other scenarios.
Supports capacitive touch operation and knob input. The knob supports clockwise and counterclockwise rotation and full press operation, smooth feel, and various interaction methods.
The 5V charging interface supports power supply and program burning, and is also equipped with three expansion interfaces of UART, I2C, and FPC to meet development needs.
The atmosphere light design adds a cool feeling, and the low power design makes it suitable for smart home appliances and portable devices.
It supports Arduino IDE and the LVGL library; you can design the UI interface yourself. It is an ideal platform for DIY projects like a mechanical keyboard knob.
ESP32 Display - 1.28inch rotary screen is not just an interactive module, but an intelligent interaction solution that combines high performance, multi-function, and ease of use. Whether you are an IoT developer, smart home enthusiast, or professional, you can find an efficient tool that meets your needs.
