I got this message on here after we discussed the Linx in a thread back in January 2018:
Just dropping you a note because you wrote the most technical response to the launch of LINX that I have seen yet.
FYI, the screen is an Android device that we modified with a 4WD-worthy integrated mount system, and we stepped up the working temperature and battery quality markedly due to it being left in a hot windscreen all day.
The controller is actually Arduino based - so you were close on the Raspberry Pi suggestion.
It is BTLE and/or USB serial linked to the screen. Whatever it finds it connects by.
The controller firmware is reflashable via either BTLE or USB link, so you don't need a laptop for upgrades.
We had to write our own Arduino bootloader to be able to do that via serial connection.
I'm expecting the geeks in the robotics labs to come chasing us for that one!
The controller stores all values and settings and keeps executing with or without screen link, so a stolen screen can simply be replaced and re-linked to continue where you left off.
I hope that clears it up a bit for you.
