For example, the solar option for Artemis (or any other board it seems) requires a 10W panel.
I am interested in an indoor energy harvester like the TI BQ25570 or the Epeas AEM10941. This way I can use amorphous panels.
Also, I would like to add more RAM, maybe something like 8MB SRAM: https://www.cypress.com/file/44066/download
I have no idea how to put these together, but I would like to build a nano-powered Raspberry Pi-like laptop motherboard with an OS that runs in initrd like tinycore linux: https://hackaday.io/project/177716-the- ... kic-laptop
For the display I would like a MIP display connector like : https://www.arrow.com/en/products/lpm02 ... isplay-inc. I understand it would be really complex but of course it could be a general purpose board with quite a bit of compatibility for various displays and systems- tablets, phones and laptops!
