I checked this on a VOXL 2.

Adding a second subscriber to /run/mpa/mobilenet_tflite_data is a clean fan-out. The Modal Pipe Architecture creates a separate client connection for each subscriber, so the second subscriber does not consume or steal messages from voxl-tflite-server or from an existing subscriber. I tested this with an existing subscriber already running, then attached another subscriber to mobilenet_tflite_data. The system continued running normally and both consumed messages. See picture below.

Only caveat is normal concerns about load and that a slow subscriber can miss data but won't affect other subscribers/server.

The qrb5165 emulator should support the MPA/libmodal-pipe itself. The pipe can still exist without the board. However, mobilenet_tflite_data will not appear in the arb5165 emulator without additional setup. That pipe is published by voxl-tflite-server, which itself consumes a camera input pipe. The emulator does not provider an emulation of the physical VOXL2 camera pipeline by default. For simulation, I would start by testing the subscriber against recorded or synthetic MPA data rather than trying to emulate the full camera pipeline.

Best,
Sean

Please take a look at the ESC firmware changelog:
https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/blob/master/voxl-esc-tools/firmware/FIRMWARE_CHANGELOG.md

support for the M0138 FPV ESC has been added in firmware V39 RC10, which is likely what you received (i assume the ESC is reasonably old, since we are now shipping with latest firmware)
please note that only starting version V39.15, the ESC firmware sends back the exact version in format Vxy.ab -- so 39.00 could mean 39.10-39.15
also note that the firmware hash that you have (e4f576a0) is not listed in our firmware changelog, but it is essentially the V39 RC10 release (39.10).

We will look into the changes. To help with this, are you able to share the approximate motor specs? (motor kv and what supply voltage you are using)? We can try to replicate.
Are you able to test the firmware from this release and tell me how it behaves? https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-esc/-/tree/366d652e3680bb769d87dfca94f76b226481a6db/voxl-esc-tools/firmware . Initially we had a few releases that were not documented in the changelog (v0_39_RC10_a7f0bccb)
Thank you
Alex

understood and checked out.  I've confirmed the umcc(u.fl) connection is fully seated and no damage is present anywhere.

If the transmitter is showing signal but the drone is not responding it's possible you are bound to another transmitter.

this is a state I will confirm.  So far though, I believe the failure mode is observable with no other transmitters powered, but i will confirm.
Thanks.

From a hardware standpoint, the 200mV droop you are observing on VDC_5V_LOCAL and VDC_5V_LOCAL_USB1 during ToF activity is not a concern at the rail level. That kind of transient is most likely localized contact/pin loss at the connector interface rather than a bulk supply issue. On a 5V rail, 200mV is well within normal operating margin. The eFuse on that rail does not assert until approximately 4.4V, so a 200mV droop from 5V puts you nowhere near that threshold. Downstream logic is regulated from a 3.8V VBAT rail that has demonstrated margin well above the minimum needed, and that rail is permitted to droop past 3.3V before any real issue occurs. The ToF-induced droop is not your RC dropout culprit.
Additionally, the M0129 VOXL Mini ESC power stage has been proven to the same load capability and test rigor as our standalone M0041 power module, using the same parts, so the supply itself is not a suspect to me. Would hate to see you chase a red herring.
The I2C errors and UART dropout sequencing are worth looking at together as they may share a common upstream cause. Beyond that, this one is likely better handled by our software team who can dig into the dmesg and service state in more detail. I will flag this thread for them.

There a lots of questions, let me start with what I can answer right away and will go from there.

Hires Video

Resolution:

Starling 2 Max comes with dual IMX412 cameras (front, down-facing). IMX412 maximum resolution is 4056x3040, which is larger than 4K. 8K is not supported on Starling Max. In general, we do have support for one 8K camera (OV64B), which has maximum resolution of 9248x6944 and that resolution is supported only at 10FPS. The only way to get that camera right now is part of a Flir Hadron combo (Boson + Color camera), which is probably not what you are looking for. So the best bet for Starling 2 Max is to use the provided IMX412 camera.
you can see some details regarding operating modes of IMX412 camera here : https://docs.modalai.com/camera-video/low-latency-video-streaming/#imx412-operating-modes

Data Pipeline:

our camera server application (voxl-camera-server) can publish processed YUV images via shared ION buffers (zero copy) and the user application can receive those buffers for processing without any cpu overhead for doing inter process communication to send the image data.
you can also publish raw Bayer data (the exact data that comes from the camera) if that's what you mean by "raw"

Optics:

no optical zoom is supported on any of our cameras, only digital


Onboard AI Compute and Performance


I will need to check with colleagues and follow up.


Flight Range, Autonomy &amp; Control


Starling 2 Max used PX4 as flight controller, so all the standard flight modes are supported

Answers to additional questions

Camera and Zoom integration: yes, raw and yuv frames can be shared with customer's C/C++ applications via shared buffers (or regular buffers via named pipes, which will have a lot of overhead for duplicating the data). No optical zoom is supported.  Examples are available upon request
We provide voxl-cross docker image which can be used to build the projects for VOXL2. Majority of ModalAI packages that run on VOXL2 are built using this cross-complier environment and can serve as examples how to build your own applications (you can find most packages here : https://gitlab.com/voxl-public/voxl-sdk)
you can mount more hardware on Starling 2 Max, see the following thread regarding flight time : https://forum.modalai.com/topic/3732/starling-2-max-payload-capacity-and-flight-time-impact

Frequency selection

when you configure your starling 2 max (https://www.modalai.com/products/starling-2-max) , you can select several options and the SKU will change accordingly. The page also has explanation for the different SKU options, so it sounds like you will need:
MRB-D0012-4-V4-C28-M11-T9-K2
C28 : dual tracking and dual hi-res cameras
M11-T9 : Microhard and Microhard pMDDL2450 and Ghost Atto (2.4Ghz)
it seems that this would be a custom SKU that you would need to request a quote for : https://www.modalai.com/pages/contact-us

Ground Controller:

If the drone ships with an RC transmitter, it should be already bound to the receiver.
the controller and receive depends on the selection, see above regarding SKU and the shop page for more description
note that the RC controller has no ability to display video, so there is no out-of-the-box ability to stream video without additional setup, such as external computer, display / goggles, etc.

I hope that answered a lot of your questions, please let us know additional questions or need clarification regarding anything else.

Sorry for the confusion about the lens change. Please see the details below.
The original lens in the IMX412 modules (M0107 and M0161) had manufacturing issues where the internal components of the lenses were loose and vibrating in flight, causing shaky video.
Due to quality / vibration issues of the original lens (part number M10000580) shipping with IMX412 (M0107 and M0161) modules, the default lens was changed to M10001028 (late 2025). However the new lens does have much narrower FOV. When purchasing the standalone camera, you have a choice of lens:
M0161 with old lens (wide) : MDK-M0161-1-07 (3.1mm EFFL, M10000580 lens)
M0161 with new lens (narrow) : MDK-M0161-1-08 (3.24 EFFL, M10001028 lens)
It seems that there maybe some discrepancy in the manufacturer stated EFFL for the new lens (3.24 vs original 3.1) because the actual FOV change is more significant than the change in the effective focal length would result in. We are looking into this.
Starling 2 and Starling 2 Max drones are currently shipping with the new lens (narrow FOV).
We do currently have stock of the old (wide) lenses that should have no issues (according to the manufacturer), however we cannot provide any guarantees for this lens due to past history of issues. If you would like to update your drone / camera with the original wide lens, please contact us and we will make it available for you to purchase (lens part number M10000580).
