One of the first true low power displays for the Pi Zero mini computer
Mimics the appearance of ink on normal paper
ePaper reflects light, just like ordinary paper, and is capable of holding text and images indefinitely, even without electricity
1.44" diagonal and 128 x 96 resolution ePaper display
ePaper is a display technology that mimics the appearance of ink on paper.
ePaper reflects light just like ordinary paper and is capable of holding text and images indefinitely, even without electricity.
All signals are broken out to a 40 pin female header.
The display included in this offering is a 1.44" diagonal and 128 x 96 resolution true ePaper / eInk graphical display.
The display does not require any power to keep the image
