The Elecrow CrowPanel ESP32 4.2” E-paper HMI Display with 400*300 Resolution uses advanced electrophoretic technology with a hard-coated anti-glare surface for clear visibility even in sunlight. Powered by the ESP32-S3 chip, it delivers fast, stable SPI communication and supports high-resolution (400×300) black-and-white display.
Equipped with multiple interfaces (GPIO, UART, TF slot) and buttons (home, back, rotary switch), it ensures easy development and operation. Compatible with Arduino IDE, ESP IDF, and MicroPython, it offers wide compatibility and ultra-low power consumption. Ideal for shelf labels, price tags, e-readers, and smart devices, it features long battery life and retains content even without power.
Features:
- 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
