VOXL 2 Image adapters handle all needed connections to our Image sensors. We cannot give guidance on designs used to replace a VOXL.

We measure RPM using the ESC, it's very accurate and part of our testing qualification on each board, it's very accurate. We do not use any other form of tach.

No, there are no official prop guards for Starling 2 Max

Please refer to the datasheet for CAD files: https://docs.modalai.com/starling-2-max-datasheet/

It is not designed to carry a payload, so you will need to perform the engineering yourself

Lead time is about 60 business days currently for all configurations.

Hi @elvis-bicharri
OK, it's a big one (~385MB), so please be patient.. but our team got the full Starling 2 Max 3D step file for you. I hear it is the latest, but this is not my domain.

Here is the link...https://storage.googleapis.com/modalai_public/modal_drawings/MRB/D0012 Starling 2 Max 11-6-26.STEP
We hope this is what you needed.
Let us know if we can help for anything else.
New posts are always best for a change of topic.

Thanks!

Sorry @pxiao This is not something we can support.

Assuming your Stinger SKU contains an ExpressLRS modem (ModalAI M0184 Gemini RX), you will want to follow the ExpressLRS Binding procedures. Firstly, to put the receiver into "binding" mode, you'll want to either press the bind button for at least 1.5 seconds, and you must do this at least a few seconds after the battery has been inserted (or anytime later). You can also put the receiver into binding mode by powering on and off the Stinger 3 times quickly, though this can be unreliable.

You will also need to make sure your transmitter is compatible with the receiver, and in a compatible mode. The M0184 by default comes with firmware based on ELRS 3, so you will need to verify that your GX12's internal ExpressLRS firmware is also on major version 3, otherwise you will need to downgrade to V3. Furthermore, the GX12 comes with a dual-band transmitter which supports 2.4GHz and 915MHz operation. To work with the M0184 you must make sure the selected "RF Band" parameter is "915 MHz", and the packet rate is 50 Hz 100 Hz, or 200 Hz. Other packet rates are not supported on the older modem in the M0184.

Hi @pxiao
2. The M0155 J2 table is the correct pinout for connecting M0161 to a VOXL 2 camera group over MCBL-00084. Matching it is necessary but it is not the whole design, and we cannot confirm a board we have not reviewed.

The answer depends on your architecture, and that has not been clear from your posts. If you are connecting M0161 to a VOXL 2, there is nothing for you to do. If you are designing your own host board to drive M0161 directly, the answer is different and we cannot offer guidance for a VOXL workaround.

Hi @김다연
The INA260 is not supported. M0041 is designed around the INA231 and our power monitoring software expects that part.

The two are not drop-in compatible. They differ in register map, device ID, and the INA260 has an integrated shunt rather than the external shunt the M0041 uses, so it is a board change as well as a driver change. Supporting it would require a new driver and a new M0041 variant, neither of which exist.

If you need power monitoring on VOXL 2, use M0041 as designed, or take battery voltage and current telemetry from our ESCs, which report it over the ESC UART.

Hi @김다연
Both are enabled by default. If a QUP appears in the table with a device node, it is enabled in the shipped image. No device tree changes or additional hardware configuration required.

UART7, J3 pins 3 and 5, /dev/ttyHS1, sys image 1.3+
UART13, J5 pins 97 and 98, /dev/ttyHS3, sys image 1.5+

Full table: https://docs.modalai.com/voxl2-qups/

Note UART13 requires system image 1.5 or newer. Check voxl-version on your unit before wiring it up.

MCBL-00084 mapping and impedance

The cable is a straight 1:1 pin-to-pin, 26 conductors, fully populated. We put the pinout variation in the adapter boards rather than the cable, so the cable never remaps anything.

On impedance, the two figures in your question are not both true of the same thing. Micro-coax is not strictly impedance controlled by definition. Each conductor is an individually shielded 50 Ω coax, and a MIPI pair is carried as two independent conductors rather than a true coupled 100 Ω differential pair. Design your board to 100 Ω differential and treat the coax run as a tolerance contribution.

180 mm is our production maximum and we do not qualify or sell beyond it.

DF56C-26S-0.3V(51) signal order

Yes, that is the correct mating receptacle. Signal order is per adapter and camera group, not per cable. The M0155 J2 table is the right reference for a single-sensor connection.

Pin 25, VPH_PWR

VPH_PWR is not intended for customer use.
