On the project, I am working on for my university we want to control a parafoil with servos connected to the Navio2. The parafoil/servos won’t be controlled. It is autonomous.
We are working with HS-7954SH servos with the operating voltage range 6V-7.4V (https://hitecrcd.com/products/servos/premium-digital-servos/hs-7954sh/product).
On the documentation for Navio2, it is said that for high voltage servos a power separation board should be used. I am new to electronics and I don’t really see what it is.
What do I need to do this? If I do this power separation board will I still need the BEC?
