Hi @dongsup-seo
It's a fair question but please provide some context for your concern.
Aside from the boot image needed (see link below), the design changes are largely transparent to the end user.

Hi @voxltester
Please take a look at this old thread: https://forum.modalai.com/topic/1356/sentinel-drone-randomly-reboots?_=1673383475709
Let us know if that issue with J5 is what is happening.
It is unlikely you are pulling too much current in normal operations as you more than likely have a fault if you think the 5V is drooping.
Thanks!

Hi @Alex-Kushleyev
That's correct, since we have not supported it or tried it, there is no elegant HW solution.
We've recently completed the M0172 adapter which breaks out a uCOAX on the upper group + 40-pin Molex (for ToF) on the lower group from a single camera group.
We have not made this product available yet for purchase, but looks like this:
If this is something that interests you, I encourage you to ask our sales team using the contact page about it (we should have a bunch in stock it just has not been a priority for us): https://www.modalai.com/pages/contact-us
We are really only anticipating 1 ToF per system. Not sure if any SW efforts have even tried more than 1 and if it's not on our roadmap, it could take a while to support.
However, if a second one is needed it would need to be on a separate camera group on VOXL 2 (not VOXL 2 Mini, as there is not enough system current at 5V to drive two ToFs reliably due to their high current demands).
Hi @Jetson-Nano
Please see this cable page for more guidance.

Doodle is one of those applications which we give customers enough to start trying it, but we encourage a custom solution to fit your application(s).
Thanks!

Hi @antenna-eng ,
@tom has you covered, I was just expressing my experiences with WSL in the hopes it helped.
Thanks!
Hi @dew54 ,
Are you willing to share your schematic with us? We always perform a courtesy review of any customer design.
What Alex said is true but there are some more subtle nuances because our Microhard design pre-dates Voxl 2. Everything was designed to be backwards compatible but a custom design can certainly step on some toes of the 5V network.
Let us know if you are willing to share and we'll email you to exchange the Sch.
Thanks!
Hi @voxl-phoenix
Yes, that M0177 flex you have plugs direct into the M0173 board 40-pin connector here: 
Please pay attention to the "+" and "-" notes in silkscreen for proper orientation.
Hope this helps!
Thanks!
Hi @antenna-eng
I've tried WSL for years internally with no luck.. it just does not work!!
It's worth buying a $300 Ubuntu laptop and know your issues may all be solved!!! I just searched AMZN and found some for less than $250!!!
@voxl-phoenix And I want to add that the two adapters (M0084 and M0135) on the bottom of your image are not used at all in this system.
Hi @voxl-phoenix
Please see these notes from here: https://docs.modalai.com/M0178/
So, you have several options of different HW to buy...
The easiest which gives you more support of other image sensors is the Starling Front End Imager Unit, M0173: This link is without any extra image sensors ...
https://www.modalai.com/collections/image-sensors/products/m0173?variant=48528274391344
Most variants include that exact set of ToF components you have, so you could get the version with tracking/HiRes sensors if you need that capability: 
(note, the $79.99 is just board only and not updated since I did not click through the option).
Hope this helps!
Sorry @Jetson-Nano , this is not my area of expertise (anything software related, I'm just hardware). Hopefully someone else from the SW team can respond shortly for you.
Hi @Jetson-Nano
No difference in data rate on any MH board. They are all USB2 rates.
Hope that helped!
Hi @Jetson-Nano
Let me try to clarify to help:
The "-3" Plug in board variant https://www.modalai.com/collections/expansion-board/products/voxl-microhard-modem-usb-hub does this:
However, the "-2" Standalone Module https://www.modalai.com/collections/modems/products/mdk-m0048-2
.
That connector provides power to the MH radio AND power to Downstream USB devices.So, if you originally had a -1 variant that you plugged into VOXL 2's J3, and you want to remove that interface, you will need to switch over to the -3 hardware variant product.
I think that was the info you were looking for and I hope I clarified that for you.
Hi @Jetson-Nano
If you do not use the J3 from VOXL 2 to power your Microhard that is the "-1" variant, you cannot power peripherals. You'll need to use the -2 variant with the red connector: https://www.modalai.com/collections/modems/products/mdk-m0048-2
VBUS in to the MH is not used for powering downstream USB VBUS ports.
Hi @Jetson-Nano
Can you elaborate what you mean by "main" vs "aux"?
We provide 8 channels of PWM as you may know. Are you asking if we provide more than 8 natively?
Hi @FIREBIRD
I answered on your other post: https://forum.modalai.com/topic/4098/power-module
Hi @FIREBIRD
Our standard power module is the same for VOXL 2 and VOXL 2 Mini. We just change the voltage settings.
Here is the link and the best we have is a PCB step file for this design (board only, no cables):
https://docs.modalai.com/power-module-v3-datasheet/
Hope this helps!
Thanks!
Hi @Jetson-Nano
I think that can work. As long as your UART matches the voltage levels indicated here: https://docs.modalai.com/voxl2-connectors/ Voxl 2 does not know (or care) which carrier board you are using.
However, we cannot speak to the quality of that carrier board and if it can provide you all the features you desire, but we trust you know this already as a seasoned user
