The Elecrow CrowPanel 1.28-inch and 2.1-inch HMI ESP32 rotary displays are compact, round touch-enabled modules designed as interactive human-machine interfaces for IoT, smart home, and embedded projects.
Both combine a high-quality IPS capacitive touchscreen with 16MB flash, 8MB PSRAM, integrated WiFi, and Bluetooth LE, powered by the dual-core ESP32-S3 microcontroller. For flexible control, a rotary knob enables touch, pressing, and twisting inputs. While the 2.1-inch model increases to 480×480 resolution with a greater viewing area, the 1.28-inch model provides a 240×240 resolution display in a smaller form factor.
They include programmable reset/boot buttons, 5V power input, an FPC connector, UART and I²C interfaces. Operating assistance ranging from −20 to +65 degrees C allows these modules to be used in smart house controllers such as thermostats, illumination or media dials, and custom audio. interfaces, portable IoT devices, industrial control systems, and DIY projects demanding a small but strong display-and-control solution.
You can get to know about many ESP32-S3-based products that we have previously covered, such as the Air quality monitoring kit, the Wireless LoRa module, the WiFIRCard, and others. You can also compare these displays with the above-mentioned products, if you want.

Both the 1.28-inch and 2.1-inch rotary displays provide a wide range of development tools and frameworks thanks to the ESP32-S3 microcontroller. Novices as well as seasoned developers will find flexibility using Arduino IDE, ESP-IDF, MicroPython, and PlatformIO. Because they work with the LVGL (Light and Versatile Graphics Library), creating smooth and interactive UIs is easy when creating modern graphical user interfaces. Furthermore, integrating well with ESPHome and Home Assistant, they provide for rapid installation for smart house automation projects without much coding needed. This mix of software support renders the modules appropriate for industrial HMI applications, smart home devices, DIY projects, and IoT prototypes.
Elecrow’s website presently sells CrowPanel rotary displays at $29.00 for 1.28-inch and $35.70 for 2.1-inch. Both modules are available from numerous sellers. Depending on the seller and shipping choices, prices typically vary from $45.59 to $48.29. Normally, it takes 2 to 4 weeks, depending on the seller’s location and chosen shipping method. India receives shipping. Prices and availability might differ even though other vendors might also carry the CrowPanel series; hence, it’s best to inquire at local electronics stores or Online marketplaces for the most current stock and pricing information.
