      Hi Modal AI team,

      My question is can the M0065/PWN Breakout power PWN connection for servo (signal, power, ground).

      Is there a threshold for motor power requirements to where for smaller servos an external power source isn't but it is needed for larger servos? Can you clarify what is recommended?

      Thanks!

        @MattB69 ,

        The 5V output on M0065 (10-pin connector with pwm outputs) should not be used to power any servos. The 5V signal is generated from 3.3V (coming from VOXL2) using a step-up converter, only capable of 80mA output).

        https://docs.modalai.com/voxl2-io-datasheet/

        the 3.3V (which is coming from VOXL2), also should not be used to power servos, as that would be risking bringing down a major power rail on VOXL2.

          Thank you so much for the reply! Your answer makes sense. My only question is that the wiring diagram is misleading from the D0015 setup. It seems that for these servos that the wiring diagram does not show an external power source. Can you confirm that the diagram needs to updated, or is this an edge case (due to maybe a smaller servos used) where those servos can be power from VOXL2/IO/PWN power (for just the D0015 use case).

          Or possibly that this diagram intentionally also shows compute logic and it needs an ESC. Can you also confirm if true that the ESC was initially left off diagram?

          Take a look:

          Once again thanks for responding, I absolutely love using your guys stuff - it makes everyone's stuff look bush league.
