The 4.37-inch E-paper module from Waveshare is an electronic paper display with a resolution of 512 × 368 pixels and four colors: red/yellow/black/white. It has a low power consumption, a wide viewing angle, and a paper-like effect without a power supply. It's ideal for price tags, shelf labels, industrial displays, and more. The module includes a SPI interface, which is compatible with various controller boards such as Raspberry Pi, Jetson Nano, Arduino, STM32, etc. It comes with development resources and a manual (driver board schematic, examples for Raspberry Pi/Arduino/STM32 -> can be found in the Quick Start Guide). 

Features: 

• No backlight, the display shows the last content for a long time even after being switched off 
• Very low power consumption, power is basically only needed for refresh 
• SPI interface, for connecting to controller boards such as Raspberry Pi/Jetson Nano/Arduino/STM32, etc. 
• Onboard voltage translator, compatible with 3.3V/5V MCUs 
• Comes with development resources and manual (driver board schematic, examples for Raspberry Pi/Arduino/STM32)
