Hi @Jeremy-Frederick @valvarez
ModalAI has not designed any power supply reference voltages on JST connectors as a REF or Power Tap Off as capable of powering servos.
If you wish to power micro-servos then please do so at your own risk. However, you may likely damage your ModalAI hardware since we do not have any back EMF/Stall/Load dump protection on any of our JST connectors.

Servos need to have their independent supply from your system battery.
Apologies we have not made that clearer in our Tech Docs.

Thanks!

Hi @Zachary-Lowell-0 , @valvarez
ModalAI has no design capable of powering servos directly.
Every servo requires independent power.

Thanks!

Hi @cobbp
It's the 2.96V directly from the Snapdragon PMIC as you noted, and SD Cards from UHS I and onward negotiate their link speeds and I/O voltage. So, a proper 1.8V SD card will internally use that 2.96V and create the 1.8V I/O rail.
For cards that operate at "3.3V", they are claimed to be supported in the Snapdragon chipsets at this lowered ~3V rail.
The slot on M0062 actually accepts UFS or uSD.

For more details on just the SD portion, please see this design where we opened our Schematics. In this case, this is just uSD, but otherwise matches the M0062 exactly for uSD functionality: https://docs.modalai.com/voxl2-dev-test-board/

Hope this helps!

@Hung-Pham said in Pinout Description of Image Sensor 4k High-resolution for VOXL (MSU-M0024):

• what is the frequency of pin CAM_MCLK0_BUFF?
• Can I change the frequency of pin CAM_MCLK0_BUFF?

Thank you!

Most MCLKs are 24MHz.
No, unless you build the kernel on your own. It is not something we will be able to do by default. However, a few customers have contracted with us to do custom driver work.

Thanks!

HI @v_v_ramarao
Appreciate your feedback again. Should you wish to design any of your own adapters until ours are released, always reach out and we are happy to do any design reviews for you! It's a service I do as a thanks for your continued support.

Hi @Hung-Pham
Can you please share more details of your setup?
Pictures, hardware components, and other relevant configuration will help along with versions of all your SW using "voxl-version". From there we can see if I can help, or I need to pull in someone from SW team.
Are you using ModalAI based RB5 platform? We do not maintain third party support of other RB5 platforms.

As a reminder, here are our supported camera configs: https://docs.modalai.com/voxl2-supported-architectures/

Hi @groupo
I bumped this thread internally for you. Hopefully someone responds soon.
Sorry for the delays and thanks for your patience.

Hi @v_v_ramarao

(Talking of PCB layout one more thing needs your immediate attention. On Voxl2 mini with J6 and J7 one has to use your interposer (splitter) board, in which case you can't use that respective main board-mounting hole... It fouls. This is the case with either of the interposer boards, single /dual.. It is road-block to use even a single camera with mini. It is very surprising that the spitter boards are not redesigned yet... A minuscule task to address such a glaring fault, is not undertaken yet)

Thanks

We appreciate your comments.
Please understand a few things about our one of our primary business models and goals. We help accelerate customer's time to market with their products, for their use case, by offering hardware and software solutions that let them develop and solidify their architectural needs. Then, when they have what they need functioning, they transition that into their custom final and elegant Industrial Design that meets their product constraints. Most often, this does not include any of our adapters, flexes, or cables. We cannot meet most customer's final goals, so oftentimes we just use what already works to meet those development goals and help you along. This is akin to any EVK/DK you buy now for any MCU, sensor, or auxiliary component when doing proof-of-concept work. In this case, yes, we know the camera splitters and adapters are not ideal for V2 Mini. They were designed for VOXL 2 (full size), not the Mini, but they function and help customers accelerate their plans. This is not an oversight nor a fault.

All that being said, VOXL 2 Mini is getting a refresh:

and we do expect volumes to pick up this next year, so we are making more adapters specifically for VOXL 2 Mini.
For example, we already have in our labs and functioning the equivalent to this coax breakout kit but for M0104/M0204: https://www.modalai.com/collections/image-sensors/products/m0173?variant=48528274391344
but we are just not ready to release it yet, even in Beta status.
We also have a single 40-pin + DF56 coax adapter (M0172) and ones for IR sensors on the horizon for VOXL 2 Mini. However, again, these are not just ready yet but expect to be live in the next couple of quarters.
These may be more suited to some customers applications since they better mate with V2 Mini and the mounting hole support.

We appreciate your feedback and let us know if there is anything we can do to help!
Thanks!

HI @TomP
Please remove all products off of the ESD static bags.
This bags are only used for unpowered storage/shipping when outside of a controlled ESD Work Area.
This site has a few good books you can try to pick up so your team is well prepared for ESD handling: https://www.techni-tool.com/category/Static-Protection/ESD-Training-And-Awareness-Materials

Hi @henrytrinh
For us to do that there is a significant validation NRE needed and then a minimum commitment buy.
This would not be a cheap option.
Likely well above $25K validation effort, possibly more. 200 units+ MOQ for starters most likely. Our standard builds are above 500 units.

If that is something you are willing to think about, feel free to reach us on our contact page and we can work up a quote for you. Do not "quote" my numbers above , but it is in the magnitude you need to be thinking about for this customization.

Hi @Jetson-Nano
Sure, here are a few key pointers:

1. The M0130 has Qty-3 USB ports. The 4-pin ones can provide 1A and the 10-pin one can provide 2Amps.
   So depending on your flavor of Microhard module, pick accordingly:
   https://docs.modalai.com/expansion-design-guide/#usb-expansion-over-j3--j5
   Refer to the table that shows this:

2. For the MH carrier, be sure you order the standalone variant: https://www.modalai.com/collections/modems/products/mdk-m0048-2

3. For cabling, you can do a few things here:
   Depending on if you use the 10-pin JST or the 4-pin JST, you might want to pick up these cables:
   https://docs.modalai.com/cable-datasheets/#mcbl-00080
   https://docs.modalai.com/cable-datasheets/#mcbl-00071
   and for power, since our MH board does not accept power over the USB, you need to use our 5V RED JST format here: https://docs.modalai.com/cable-datasheets/#mcbl-00017 or here: https://docs.modalai.com/cable-datasheets/#mcbl-00095

(EDIT/ADD) --> To clarify further, you can use the VBUS from M0130, but you need to splice into the red JST. Or, you can use MCBL-00095 and feed off of our 5V power module format directly and have no current limitations (up to the limits of the power module of course, but I do not think MH can do more than 10W anyway).

If any are not listed on Shopify (our sales website), please just reach out to using our contact page for a quote and that will also prompt the team to get it listed too for easier future purchases: https://www.modalai.com/pages/contact-us

Hi @Jetson-Nano
Yes, sorry for not following up. We have a small batch tested and in inventory now. I think our team may not have it up yet in Shopify, so you can always reach out directly asking for a quote using our contact form. I alerted the team your request may be in-bound.

Hi @jonathanrblazer
Yes, do a dual boot. It's what we do in our HW lab and we have no issues.
WSL just does not work the way it needs for our Ubuntu flavors.
Hope that helps!

Hi @Chase-Riley
Your best bet might be to start a new thread, that will help ensure you get more eyes on it for the best person on our side to help you along!
Thanks!

@groupo said in Starling 2 max information:

Is the starling 2 modem the Sierra or the Quectel?

I can quickly answer that one... we no longer carry the Quectel Modem and are sticking with NDAA compliant versions going forward.

I will let the rest of the team answer your other questions.
Thanks!

Absolutely! @Jeremy-Frederick
That is why we keep the 6A part to match our Power Module capabilities from M0041.
We need 6A to deal with inrush power-on for our VOXL 2, but then after that, we usually only pull 6-8W MAX in the most extreme use cases, so you have over 20W of "free" power to use on accessories.
Hope this helps minimize your system eBOM!
Let us know if you have any other questions.

Hi @Jeremy-Frederick
If you mean "2A" (not 5A) then sadly no.
Our newest 4G modem board M0130 can provide the needed 2A (10W) for full range, but otherwise, an external supply is needed for Doodle to achieve their max stated specs.

HI @Jeremy-Frederick
This cable may help improve your setup to get rid of that external regulator for the MH
https://www.modalai.com/collections/cables-1/products/mcbl-00095
Food for thought.

Hi @voxl-phoenix
In all honesty, you may just want to purchase a VOXL-2 based flight deck. None of your image sensors from VOXL Flight can directly plug into VOXL 2. You need at least a few adapter PCBs or flexes and you need to make sure all the image sensors you want to port over are supported.
The best way to do this is to have a new freshly built and tested flight deck. Then, if you notice any sensors are compatible with what you already have, then you have spares.
It usually takes some effort to get image sensors working exactly the way you want, and with a flight deck pre-tested and confirmed, you are starting off on the better footing compared to trying to build your own from scratch and chugging through it.
Check these out and see if the benefits add up for you.

Hi @Jetson-Nano
It's a catch-22.
Our ME team is well versed to design these as trapped as best as possible to prevent back-outs in certain areas. In others, we need them accessible by you, the user, to have design and development freedom. So, we just need to caution developers to be very careful.
We have not put these through the ringers or any specific MIL-STD testing as this is a new roll-out, and many customers were enthusiastic about it and were asking for this for years.
We are doing what we can to support the demands and then also highlight the risks.
It's all about trade-offs for smaller and cost-sensitive vs rugged reliability. We leave many decisions up to customers by offering options and at least showing what is the smallest possible approach for those that care about that. Smallest is usually the hardest constraint to meet.
