Hi, first of all nice to meet you all, this is my first post.

As stated in the subject, my dream is to create a 7" PDA-phone like the Gemini PDA (https://store.planetcom.co.uk/products/gemini-pda-1) or better the "now crowfounding" Cosmo Communicator (https://www.indiegogo.com/projects/cosm ... #/comments).

Ok, I know this is not a simple project, but that is what I need: an all-in-one 7" notebook + smartphone + physical keyboard. So, why not to buy the Cosmo Communicator? Since I think it has a main drawback: I don't want to "open it" just to answer a simple Whatsapp message while I'm walking: the 2.5" display on the front simply (obviously) won't support an "on-screen" keyboard.

So I studied a case where the (single) 7" LCD is on the front, and the keyboard simply "slides out" from the bottom, while lettin you tilt the screen (I don't know if I made it clear...)

Anyway: do you think LattePanda could be the right board for this project? Those shoud be the "main" components needed:

- board
- LTE shield
- 7" LCD touch screen
- keyboard
- battery

But here is the "first main" question I'm thinking about:

will the installed Android be capable of managing the rest of the hardware? Mainly the LTE shield: I was thinking about an Arduino shield..., but also the 7" LCD touch screen)

This is only the question I'm thinking about right now, but I know there's a lot of other problems.

So please let me know what do you think about it.

Thank you.

Interesting project. Looks like that Cosmo is Android based system. Though technically, LattePanda works with Android. But official team didn't support that. I just saw some test like Phoenix OS and Remix on LattePanda. Not sure if it works perfectly.

Hey i thought about this as well. However i not sure where to begin I would be intrested in joining you since my project is somewhat simular. For phone i thought about using a gsm module and a level shifter and program some AT commands to handle the phone and internet. But I would be reinventing the wheel. Then thought about using the Huawei gsm module and unlocking it to get phone capabilities. However when adding anything extra you have to calculate that into your watthours. Another issue I found is find was the right display ( my issue because i wanted a 6in phone 2k display).
