Waveshare 7.5 inch E-Ink Paper display HAT for Raspberry Pi

This is an E-Ink display HAT for Raspberry Pi, 7.5-inch, 640x384 resolution, with an embedded controller, communicating via SPI interface. This display shows the data on the screen as same as it seen on printed paper. There is no backlight so it can keep displaying last content for a long time even when the power is down. As these displays have no backlight panels and it doesn't need a continuous power supply to display the (static data with periodic intervals) data on the screen, The Display it has a great advantage of ultra-low power consumption. Also, it has a wide viewing angle, great viewing effect under sunlight, Basically power to the display is only required for refreshing. For connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.. SPI interface can be used. Features: No backlight keeps displaying last content for a long time even when poweris down Ultra low power consumption, basically power is only required for refreshing Compatible with Raspberry Pi 2B/3B/3B+/Zero/Zero W SPI interface, for connecting with other controller boards like Raspberry/Arduino/Nucleo, etc. Onboard voltage translator, compatible with 3.3V/5V MCUs Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32) Interface: SYMBOL DESCRIPTION VCC 3.3V/5V 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, high active Useful Link: Wiki: www.waveshare.com/wiki/7.5inch_e-Paper_HAT Package Includes: 1 x7.5-inch E-Ink Paper display HAT for Raspberry Pi 1 x e-paper Hat for Raspberry Pi to e-paper Adapter 1 x Interfacing Cable 1 x Nut-Bolt and Spacers set Note: No Raspberry Pi is included in Package Specifications :- Operating Voltage (VDC) 3.3 ~ 5 Display Size (inch) 2.13 Outline dimension (mm) 170.2 111.2 Dot Pitch 0.255 0.255 Grey level 2 Display Color Black and White Display Resolution 640384 Viewing Angle >170 Interface 3-wire SPI, 4-wire SPI Full Refresh Time (s) 6 Refresh Power 38mW(typ.)
