A small, open source e-paper display that is updated and powered wirelessly via NFC
This project is launching soon.
HiPo is a 3.52-inch electronic paper display module the size of a business card. Content is uploaded via NFC though a handy app. No batteries required. The development board can compile different display functions through editing the code.
NFC is used to transfer text or images to the e-paper display. Also, HiPo does not require batteries as is powered by that same NFC during transmission. This is possible because electronic ink technology can be displayed on a screen almost permanently, without an onboard battery. HiPo can be used as a badge, label or daily sticky note, as well as any other clever application you come up with.
