I am thinking of a project where i make a phone out of one of these. But i would like a bigger battery, can i just combine 2 bigger li-polymeer batteries so i still have 7.4V.
Also is it possible to use the sim card slot for cellar uses aswell? I think it might be possible if i use an other 4G module. Otherwhile i will use an external SIM reader like those you use on arduino i guess.
I like your thought but its not so easy to achieve what you are talking about.
I m. Talking from my experience in pine64 pinephone community. Pinephone is open source phone with multi os options but non have achieved making audio route correctly after almost a year of development. So it is going to take many developers to work on such device to make it possible.
If you want a working phone with full linux aarch64 os then pinephone in the only option right now.
With vim3 or edge and m2x extension you can only achieve data using SIM card.
Thank you! Guess i’ll try to mess a bit around with other SIM readers then.
I am not trying to have a completely functioning Linux phone (yet). But i once called someone with an Arduino device i made and thought it would be cool if i could do that using Linux instead. I was quite sure you should be able to connect an other SIM reader and call someone using the terminal (far from being convinient in any ways) but maybe i was too optimistic.
Ps: Wasn’t there a long waiting list on the Pinephone? Might be wrong now but i believe it was a moth ago. It looks promising so let’s hope it wont be a failed Linux phone again.
