The PaPiRus Zero case is designed to enclose the PaPiRus Zero ePaper pHAT module.
ePaper / eInk is a display technology that mimics the appearance of ink on normal paper. eUnlike conventional displays, ePaper reflects light - just like ordinary paper - and is capable of holding text and images indefinitely, even without electricity. Because of this, ePaper displays and single board computers or microcontrollers are a match made in heaven as together they use a very small amount of power whilst still bringing a display to your project.
This transparent case design it allows you to view anything on your ePaper screen without having to open up the case. You can also view the PaPiRus Zero case in 3D here!
