There'll be a new STM32 L0 (their ultra low power ARM cortex M0 series) "discovery" board, with an E-paper display on it.
I'm not aware of any nice little inexpensive devboard with something like that. Seems not to be in stores yet or not listed by google anyway(*1), but... I am quite tempted to play with that as soon as it is out ^^ For one thing b/c I think e-paper is cool, but then I'm also interested to see the power consumption of it all... So I though I just throw this in the forum.
I was able to order and receive one of each before they went out of stock...ETA for new stock appears to be September (ouch!). The e-ink display on the discovery board is pretty neat...it arrives out of the box with a demo display already imprinted on it, no power required. Have not experimented with it yet but also interested in the power consumption of both the display and the L0 MCU in general...if it meets its spec'ed numbers, it looks to be a real winner...
