Just soldered this up. It's a small e-paper device with USB, buttons, a real-time clock, FRAM, an ATmega32u4, and a rechargeable battery.
I'm trying to get USB CDC virtual serial up right now, so that I can test and debug the rest of the board, but it's proving to be a bit difficult...
I love the Pibow, by the way. ;)
Glad you're a fan of the Pibow! :-)
