It's an open-source pocketable e-paper device with an (Arduino compatible) ATmega, USB transceiver, Real Time Clock, FRAM, and coin cell Li-Ion rechargeable via USB. It also has five buttons along the top. Whole thing should be around 4mm thick. Repo here: http://github.com/Hylian/arducard http://github.com/Hylian/arducard
Some potential applications: QR codes, barcodes for rewards cards, Google Auth OTP, text terminal for a Raspberry Pi, etc.
Unfortunately, it seems I missed a certain small detail... https://dl.dropboxusercontent.com/u/538662/missedtrace.png https://dl.dropboxusercontent.com/u/538662/missedtrace.png
- asadlionpk 13y agoNice. Where do you source e-paper display from?
- mafuyu 13y agohttp://repaper.org http://repaper.org You can buy a cute dev-kit that works as a MSP430 Launchpad Boosterpack and has extension headers for Arduino, etc. off Digikey.
