Hi @Judoor-0
None of our hardware is qualified for active use during charging.
Please remove the battery prior to charging.
Thanks!

RE: Operational range of the VOXL 2 mini
Hi @Bilal-Hussain
What modem and network carrier do you have? That is what determines your range.
We only supply a method with these plug-in boards to use those modems.
That table you posted is how much current over USB each carrier board we have can provide. As long as your selected modem uses less than the rated current of our plug-in boards, then you should be able to achieve the modem manufacturer's published specs for range. -
RE: Unable to communicate with add-on board
@rogerli said in Unable to communicate with add-on board:
@Vinny I have another VOXL2 where only DS1 and DS2 lights up constantly, but D1 doesn't light up. Is this normal? (There was a slight deformation near the power interface due to a previous fall.)
No. D1 means most of the system power is good. If it is OFF, your hardware has gone bad from that crash.

RE: Unable to communicate with add-on board
Hi @rogerli
That is fine. DS2 is user controlled as per that web link above.
It normally flashes at first then goes quiet until commanded by SW. -
RE: Unable to communicate with add-on board
Thanks @rogerli , at least now we have confidence this is not HW related. Those indicators are acting normally now.
At this point, I'm going to defer to our expert @tom who can help guide you further now that we are looking more likely at SW issues.
Thanks!

RE: Unable to communicate with add-on board
Hi @rogerli
Thanks for the pic. OK good. That is all normal, and your MCBL-00001-1 is from newer stock that is much more reliable than older MCBL-00001's a few years ago.Now, regarding the specific plug-in board with Microhard, I wonder if you had an issue we are aware of as reported from previous forum users and we capture that here:
https://docs.modalai.com/expansion-design-guide/#j3j5-expansion
So, when you install the Microhard, be sure the bottom of the MH board is not touching J5. If it does, that can make the system and then LEDs go wonky from shorting out stuff and prevent you from seeing the devices with lsusb.
If you can get past all of that then someone from SW will have to chime in to help you further.
I just jump in when I see potential HW related topics -
RE: Unable to communicate with add-on board
Hi @rogerli
A red light at DS1 when powering ON implies your power supply input to VOXL 2 is not in spec.
https://docs.modalai.com/voxl2-leds/Can you please post a pic of your setup and we can go from there. No point doing any further steps until we know you have a good power module.
Thanks!

RE: Stereo cameras not working with 14.5cm extension cable
Hi @Gary-Holmgren
We wrote this up some time ago to help explain the "why" of these longer flexes not always working.
Link here
You can read in the report that not every configuration is readily supported, and may take some custom tweaks to make it work, such as slowing down the MIPI rates.
Alex has you covered otherwise! -
RE: Operational range of the VOXL 2 mini
Hi @Bilal-Hussain
I also encourage you to review our Hardware Expansion Guide.
https://docs.modalai.com/expansion-design-guide/#usb-expansion-over-j3--j5
In there you'll see how we achieve most of our expansion is by USB. So, depending on how much current your target device needs, we can power it directly, or if you need more than the posted VBUS ICC limits for the various plug-in boards, then you can just plan on providing an external power source as well.
Once you further refine your modem/radio of choice, please keep those in mind. It may make your final integration steps much easier to know this info.
Hope this helps!! -
RE: Operational range of the VOXL 2 mini
Hi @Bilal-Hussain
You are certainly veering away from the intended use cases and design goals of VOXL 2 Mini, and instead we'd recommend you look at VOXL 2 so you can use add-on boards such as Eric mentioned like Microhard or a 4G/5G solution.
Modem performance with various base stations is operator/carrier dependent and nothing we can control nor provide metrics on. VOXL 2 can interface with many modems, so I think you might want to first do some modem analysis to see what modem solution will work for your intended use case and constraints.
From there we can help you determine which platform (VOXL 2 or VOXL 2 Mini) can work with your modem and carrier network of choice. -
RE: Doodle Labs Mini Integration with VOXL 2
@Denver-Bennett Great, glad to hear that helped!

RE: Doodle Labs Mini Integration with VOXL 2
@wilkinsaf
Yes, we made sure the splices are as close to the source 5V as we could to help alleviate the 1A per pin spec on JST crimps/cables/housings.
Always check our cable pages first before thinking you need to make cables for our products.
We are (often) pretty good about having cables you need, even if we did not get them all online yet.
If not, we have very close "starter cables" to help you along.
Thanks! -
RE: Does the MDK-M0041 have a built-in automatic low-voltage cutoff to protect the batteries?
@Moderator No, it does not. You need to rely on QGC or other reporting tools.

RE: Doodle Labs Mini Integration with VOXL 2
Hi @Denver-Bennett
We made a purchase link active now for MCBL-00085-1: https://www.modalai.com/products/mcbl-00085
We do not always have all items listed as individual purchase links when they are included in kits of other items, but in your case if you already have a Doodle Labs radio, you will want this cable which comes included when you buy the radio from us.Hope this helps!
Thanks! -
RE: Doodle Labs Mini Integration with VOXL 2
HI @Denver-Bennett
I'm confident you need to use Port 1 on Doodle for the USB as a device.
Port 5 is for Doodle acting as Host.
Port 1 matches our cable configuration for MCBL-00085-1: https://docs.modalai.com/cable-datasheets/#mcbl-00085
If you did not get an MCBL-00085-1 from us with the kit, let us know and we need to make sure it available as a stand-alone item for purchase.
Hope this helps! -
RE: Powering the VOXL 2 as a Standalone Computer
Hi @Mihir-Bala
You will need a 2S minimum to satisfy all the requirements of our power module: https://docs.modalai.com/power-module-v3-datasheet/
Then, you need to do the math to support a 30Watt transient on power up... which equates to a ~5amp burst at the low end of the 2S cell ~6.4V.
So, if you have a 1,000mAh cell at 2S, that will require a 5C rating.
If you have a 2,000mAh cell, you need ~2.5C rating, and so on...Hope this helped!

RE: VOXL Mini 4-in-1 ESC no Status LED nor sound after power connection
HI @K-Stute
Glad you made some progress.
You are welcome to try the RMA process for the ESC and we can help debug it for you.
Up to you, no guarantee we can fix it: https://www.modalai.com/pages/rmaAs for loading SW and Params, I am not the best resource for that, so I'll ask someone else to chime in, or please review the many forum posts related to loading ESC params.

RE: VOXL Mini 4-in-1 ESC no Status LED nor sound after power connection
Hi @K-Stute
as long as it's not low resistance (<1kohm), the TVS/Protection diode should still be functional. Otherwise, you could see a short <10-20 ohms).
Since you have the power module in parallel with the battery leads, it is likely you have a lower reading than mine, and your DMM may be using a different technique to charge the node, so I am not worried that you have a different reading.
I do think it is troubling that your voltage drops after it is turned ON, since that is indicative of some hardware issue downstream of the power supply, or the power supply itself cannot handle the load.When you use a battery, do you still see the input VBAT drop down to 6V?
Also, to confirm, you are using a VOXL 2 with the M0049/M0117/M0134 ESC and our Power Module at 5V, right?
I ask since nothing in that configuration refers to our products as "mini" so the post title may be a little confusing. So, just wanted to clarify.The advice from our team is to disassemble (unfortunately) each item and test individually with a known good working power supply so you can monitor the current. Especially since we do not want any HW issues to propagate and cause more damage to other devices in your system.
Then, when you re-assemble and connect motors, switch over to battery power.
Hope this helped.Thanks!

RE: VOXL 2 M0135 Dual Camera Connections with M0107 and M0149 Cameras
@Alex-Kushleyev OK, I am just making sure the M0135 is not used in a cascaded mode (a M0135 plugged into another M0135). That is what the first pictures look like to me since the M0135 is just sitting open on a bench.
As far as the image sensor, all modules are tested at ModalAI HQ before shipping in a known good working configuration of hardware (i.e.: a golden setup). So, yes, all image sensors are working when shipped. Same for the extension flexes. Every one is tested before shipping.
I do see a bend in the flex right here, so hopefully that is not a firm crease since creases will damage flexes:
Hope this helps!
