🟢 Fully tested and working
A green circle means the hardware electronics or the programming code was fully tested, each of its functionalities and capabilities. And it can be installed in a vehicle. Keep in mind this does not mean errors won't happen. As in everything related to electronics and software, there are revisions and updates. This open hardware is no different.
💯 Fully tested & working, no improvements necessary - already being sold online
🆓 Fully Open hardware \ source code
🤪 There's better than this. don't use it
🔐 Fully closed hardware \ source code
⚡️ fully tested and working, however, it is a dangerous solution to deploy
🟡 Not tested. Working capability is unknown, it may work or not.
A yellow circle means the hardware electronics or the programming code was not fully tested, each of its functionalities and capabilities. This does not mean it not working, it simply means testing is needed before giving a green circle of approval.
🔴 Fully tested but not working.
A red circle means the hardware electronics or the programming code was fully tested, and found some kind of critical error or fault. This means the electronics or firmware code cannot be used in a vehicle.
⌛ Not started.
The hourglass means the hardware electronics or the programming hasn't started. Most likely because is waiting for the necessary test components needed for reverse engineering and also engineering of the new open solution.
