Thanks!

@wilkinsaf

So to confirm - it is Modal AI's recommendation that the user modifies MCBL-0089 to allow for board (Voxl 2 Pin 1) to power airspeed sensor for this configuration? (Until you guys release a new custom cable for this use case?)

@Alex-Kushleyev

One more additional question about D0015 Diagram. The diagram shows that the Airspeed sensor board is being powered by 5V spliced from pin 1 on M0054 J19 connection.

Also in the documentation, MCBL-00089 (Modal AI custom wire) is called out to be used for this connection of M0054 to GPS/LIDAR/Airspeed (see: https://docs.modalai.com/voxl2-D0015/)

My issue is that MCBL-00089 does not natively have this 5V connection pinned. See screenshot from MCBL-00089 purchase page. This also matches the MCBL-00089 that I bought.

Main question: Is the expectation that the user modifies MCBL-0089 to make this splice themselves? Or am I missing something here?

@Alex-Kushleyev

All is clear now. Thanks Alex!

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.

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!
