This is an E-Ink display module with embedded controller, communicating via SPI interface. Due to the advantages like ultra low power consumption, wide viewing angle, great effect under sunlight, it is an ideal choice for applications such as shelf label, industrial instrument, and so on.ally open interfaces.

• 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
• SPI interface, for connecting with controller boards like Raspberry Pi/Arduino/Nucleo, etc.
• Comes with development resources and manual (examples for Raspberry Pi/Arduino/STM32)

An Elegant, durable case for your Raspberry Pi 2/3/model B/B+.

• 【Removable lid】  Easy access to all connections with allowance for cable routing
• 【Two camera mounting options】 (on the base or hidden beneath the lid) make this the perfect case for use with a camera
• 【Thick-walled design】 It is strong enough and can withstand being pulled apart and re-assembled many times if necessary.

This module is designed to detect the status of the filament in case 3D printer runs out of filament but continue to print, leaving an incomplete printing that requires you to start over.

• This sensor will automatically stop the 3D printer when the filament runs out so that more filament could be loaded to finish the print.
• The module can be connected to CR-10 Plus and CR-10S directly and it also works with other clones such as CR-10 standard with upgraded main board.
• This is a must-have upgrade kit for your beloved CR-10 3D printer.
