content: Hey there,together with a colleague I'm running a crowdfunding campaign on CrowdSupply at the moment:https://www.crowdsupply.com/robert-poser/paperinoYou can find details on the campaign page or our hackaday.io project page:https://hackaday.io/project/21551-paperinoBasically it's an easy access to an e-paper display. You don't have to worry about the weird voltage levels e-paper screens need and their driving schemes. You just hook up power and SPI to our board or use our shields and you're good to go. We wrote a Arduino library and all hardware and software is open source and can be found in our GitHub repo:https://github.com/RobPo/PaperinoI know there are other e-paper shields out there so here's what makes us special:The display we use do not have a silicon based backplane on glass substrate like the others, our displays uses an organic semiconductor on a plastic substrate. They are therefore a bit more robust and even slightly bendable.With most other displays you are limited to two colours (black and white) and full updates (whole screen is flashing and updating even if you just want to change one pixel). Our display can drive 4 grey levels (including black and white) and use partial updates (only changing pixels update). Technically all e-paper displays could do that but some manufacturers don't let you access these features without signing NDAs (I don't know why, legal reasons I guess).I did some write ups on the update modes (https://hackaday.io/project/21551-paperino/log/59392-e-paper-basics-1-update-modes) and grey levels (https://hackaday.io/project/21551-paperino/log/59564-e-paper-basics-2-gray-levels).Let me know what you think.

content: Yeah, you're not the first to point that out :-)We definitely can't keep up with ST when it comes to the price.But they are also a good example of what our "competition" can't do (we are a 2 people operation, we don't consider ourselves competition to anyone). It's the 2-bit grey scale images and partial updates. As of yet I only saw 1-bit greyscale and full updates with the ST boards.
