ELECROW CrowPanel ESP32 4.2” E-paper HMI Display with 400×300 Resolution Black/White Color SPI Interface with Acrylic Case
The ELECROW CrowPanel ESP32 4.2” E-paper HMI Display is an advanced, energy-efficient display solution designed for a wide range of electronics applications. Featuring a 4.2-inch e-paper screen with a resolution of 400×300 pixels, this display delivers sharp, high-contrast visuals in a classic black-and-white format. Encased in a protective white acrylic shell, it combines durability with a professional aesthetic, making it suitable for both prototyping and end-user products.
Powered by the ESP32-S3-WROOM-1-N8R8 microcontroller, operating at up to 240 MHz, the CrowPanel ensures robust performance and reliable data transmission through its SPI interface. The display supports a variety of interfaces, including UART0, BAT, a 2×10 pin GPIO, and a TF card slot, enhancing its versatility for developers. Additionally, it features user-friendly controls such as a rotary switch, menu button, exit button, reset button, and boot button, facilitating seamless interaction and development.
Feature:
- 4.2-inch E-Paper display, 400*300 resolution, black and white, using SPI interface communication.
- ESP32-S3 as the main chip, frequency up to 240MHz.
- Pure reflection mode, no backlight required, completely relying on light reflection to display content, and the displayed content will not be lost even if the power is off.
- Hard-coated anti-glare display surface, which can keep the content visible even under direct sunlight.
- High contrast and high reflectivity provide a clearer and more vivid visual experience.
- Ultra-low power consumption and partial refresh function, significantly saving energy and extending battery life.
- Support full viewing angle, clearly visible from any angle.
- Rich buttons and interfaces (such as GPIO interface, UART interface, home button, etc.) for easy development and operation.
- Equip with Arduino IDE, ESP IDF, and MicroPython development environment for a smooth development experience.
