I have a question about powering the servo rail of the Navigator board with 5V.
For a bit of context, I am working with Blueboats for my robotics research and I will have, at some point, the need to add servos to the vehicle.
From my understanding, the servo rail of the Navigator board needs to be powered with 5V to allow driving servos, which makes sense.
Then, my question is: where can I take this 5V from ?
I see a couple of simple solutions:
The second 5V output of the powerswitch
One of the V2 5V outputs of the fuse board
Adding a new UBEC in parallel of the 16V circuit to generate a new, decoupled 5V
What is the safe way to do this ?
Hi @Loick -
I would recommend the third option, an additional UBEC, for powering the servo rail. The V2 5V outputs are limited by the 5V supply of the Basic ESC 500, and the power switch powers the Raspberry Pi 4, so you would not want to risk interfering with the quality of this power during servo usage!
Hi @Loick -
Correct - the ESC 500 BEC powers the V2 5V fuse board rail.
I would agree that a high in-rush current load like a servo is better served by a dedicated power supply though!
