Hi,
What’s the difference between open and closed hardware?
https://ardupilot.org/copter/docs/common-autopilots.html
They both run Ardupilot firmware in the end right?
What is your recommendation for rover mower flight controller this days?
I don’t need a fancy enclouser etc. Prefere a budget solution and Im not afraid of soldering 
Appreciate any suggestions.
(I need 2x rtk gps on it for yaw and planning for automatic docking to the battery charger-probably camera here, 2x hoverboard motors with TZT DC 6-60V 400W BLDC drivers?)
Thx.
