Option: No or WithDriver Board Version Options 2.15″ E-Paper (G) Low Power, Wide Viewing Angle, Paper-Like Effect Without Electricity Ideal for price tags, shelf labels, industrial instruments... Note: the driver board is optional, please refer to the Package Content for detailed part list Features At A Glance No backlight, keeps displaying last content for a long time even when power down Ultra low power consumption, basically power is only required for refreshing Comes with online development resources and manual (driver board circuit diagram, examples for Raspberry Pi / Jetson Nano / RDK X3 / Arduino / STM32) Optional for e-Paper driver board: Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards, Jetson Nano, RDK X3 Adopts Raspberry Pi HAT+ standard to improve interoperability, helping the users to design and develop faster, easy to use with other peripherals and extend more functions for Raspberry Pi Adapting SPI interface for connecting with controller boards like Raspberry Pi / Arduino / STM32, etc. Onboard voltage translator, compatible with 3.3V / 5V MCUs Specifications OPERATING VOLTAGE Raw display: 3.3V DISPLAY COLOR Red/Yellow/Black/White with driver board: 3.3V/5V INTERFACE 3-wire SPI, 4-wire SPI GREY SCALE 2 OUTLINE DIMENSIONS Raw display: 60.8 × 31.8 × 1.00 (mm) FULL REFRESH TIME 20s with driver board: 65 × 34 (mm) DISPLAY SIZE 48.10 × 26 (mm) REFRESH POWER <50mW DOT PITCH 0.1625 × 0.1625 (mm) STANDBY CURRENT <0.01uA (almost none) RESOLUTION 296 × 160 pixels VIEWING ANGLE >170° Advantages Of EINK E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper. E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect. Standard Raspberry Pi 40PIN GPIO Header Compatible With Raspberry Pi Series Boards, Jetson Nano, RDK X3 * for reference only, the Raspberry Pi in the picture is NOT included. Optional For E-Paper Driver Board Onboard SPI Control Interface, For Use With Controller Boards Like Raspberry Pi / Arduino / STM32 VCC Power (3.3V / 5V input) GND Ground DIN SPI MOSI pin CLK SPI SCK pin CS SPI chip selection, low active DC Data/Command selection (high for data, low for command) RST External reset, low active BUSY Busy status output pin Onboard Voltage Translator Compatible With 3.3V / 5V MCUs Outline Dimensions 2.15inch e-Paper (G) 2.15inch e-Paper HAT+ (G) PACKAGE CONTENT [] 2.15inch e-Paper (G) （ No PCB Driver Board） [] 2.15inch e-Paper HAT+ (G) （ With PCB Driver Board）
