Single Board Computers

Nice to haves:

Boot from an NVMe without a hat/cape/shield

Both wifi and ethernet

Hi!

My RG353M fell from a second floor and it seems the screen died. It's clearly cracked but I can make out a bit of the menu, so it's still working. I looked it up on aliexpress and can only seem to find replacement screens for the RG353VS. Is it the same screen? do you guys think it would work?

Thanks.

Rasberry Pis and similar are sometimes sold as credit-card sized, but they are not portable, really, have huge Ethernet ports and no display or keyboard. Those are on the too-big side for what i am looking for.

In the other hand, you could say that SIM cards or USB devices are technically computers, but they lack a user interface. They are too small.

Is there something small with a usuable display and input method; something that looks like a calculator or tiny smartphone? Does not need a battery (although that's a plus). Does not need WiFi or 5G (although that's plus). Needs some standard method to communicate with the outside world (USB, Bluetooth, NFC, Wifi, ...). Should easily fit in a pocket, wallet, purse.

Ideally something that can run a minimal Linux or Android?

I bought a orangepi 3 LTS and put it in a case and got a little fan to work via GPIO and got my image in a SD for the first boot. I turn it on and it has android OS v9 on it. I want to run Debian on it for some personal projects as I want to get familiar with Linux environments.

Should I be concerned it has an Os on it when I thought it was new? I have put it on my home network or connected it to anything at all.

How would I go about removing android and booting from SSD to use Debian?

Edit: I looked up the wiki and found it comes with android to test the hardware. All good

I just got an Orange Pi 4 (specifically this one) for Kodi and I am trying to install LibreElec.

I am trying to run the latest stable version of LibreElec for Rockchip (search "Orange Pi RK3399" on this page), but it is not booting.

I am able to install and run Ubuntu on all the same hardware, so my problem is the LibreElec image.

To my understanding, this should work. I have an Rockchip RK3399 based Orange Pi 4 and the image is matched to that.

What am I doing wrong and is there a better option for Kodi on Orange Pi 4?
