The 3.7″ e-Paper HAT for Raspberry Pi offers a low-power, paper-like display with a wide viewing angle. Utilizing microcapsule electrophoretic technology, it displays content without a backlight, making it ideal for applications like price tags, shelf labels, and industrial instruments. This HAT is perfect for users looking to integrate e-Paper into Raspberry Pi-based projects.

Features:

• No Backlight: Keeps the last displayed content even when powered off.
• Ultra-Low Power Consumption: Power is only required for refreshing the display, making it energy-efficient.
• Wide Viewing Angle: Offers nearly 180° viewing angle for clear visibility from multiple directions.
• SPI Interface: Easily connects with controller boards like Raspberry Pi, Jetson Nano, Arduino, STM32, etc.
• Voltage Compatibility: Onboard voltage translator supports both 3.3V and 5V MCUs.
• Standard Raspberry Pi GPIO: Compatible with Raspberry Pi series boards, Jetson Nano, and other microcontrollers.
• Development Resources: Comes with manual, driver board circuit diagram, and examples for Raspberry Pi, Jetson Nano, Arduino, and STM32.

Application:

• Price Tags: Update pricing information while maintaining low power consumption.
• Shelf Labels: Perfect for retail and warehouse applications, displaying product details and inventory without the need for backlight.
• Industrial Instruments: Ideal for low-power, clear, and durable displays in industrial settings.
• Digital Signage: Use for digital signage in public spaces, such as schedules or notices, where content doesn’t change frequently.
• E-readers: Utilized in low-power e-readers, providing paper-like viewing experience for text and images.
