Connecting MSU-M0149-1, MSU-M0107, and VOXL 2 Time of Flight (TOF) Depth Sensor

Moderator

We need to connect the following: Forward Facing MSU-M0149-1, MSU-M0107, and VOXL 2 Time of Flight (TOF) Depth Sensor
Sensor with Adapter PCB and M0177 Starling Flex (Molex 40-pin) and a second TOF Depth Sensor in the Rear of our platform as well facing downward. We seem to not be able to figure out which connector works from the TOF we have (MSU-M0178-1-01) with any of the connectors or adapter we have purchased. Do we need to instead be using the (MSU-M0169-1-01) TOF sensor and PCB? Or is there a way to buy the connector and PCB separately to use with the ones we have?

The easiest way to connect an IMX412, AR0144 and TOF would be to follow the Starling 2 architecture found here: https://docs.modalai.com/voxl2-d0014/

To just connect the TOF directly to VOXL 2, the M0172 is likely what you are looking for: https://www.modalai.com/products/mdk-m0172-1-00

@Moderator So to confirm, we need the M0173 to connect the 3 front sensors then the M0172 for the single rear TOF, what cables would we use that are the longest ones available to then connect to the Voxl2 ports?

Thanks!

BTW We currently have a hadnful of what seems to be the incorrect adapters listed here:

2x VOXL 2 Mini 40-Pin Connector TOF Adapter (MDK-M0172-1-00)
2x VOXL to VOXL 2 Image Sensor Interposer
2x VOXL 2 Dual Image Sensor Expander
2x Cable 26-pin Micro-coax for Image Sensor Modules

@QSL

For connecting the second TOF to VOXL2, you would need to use VOXL2's J8 port because J6 and J7 will be taken up by the M0173 with the three front cameras.

So you need M0172 plugged into J8 and then plug in M0177 + M0171/M0178 interposer + (actual TOF sensor) assembly into M0172. You can also use an extension M0170 instead of M0177 (https://www.modalai.com/products/msu-m0170).

using M0177:

(voxl2 J8) <-> (M0172 J1L) <-> (M0177) <-> (M0171 / M0178) <-> (TOF Module)

using M0170

(voxl2 J8) <-> (M0172 J1L) <-> (M0170) <-> (M0171 / M0178) <-> (TOF Module)

Please keep in mind that M0177 and M0171 / M0178 and TOF module are usually sold as one unit. Also, M0171 and M0178 are identical except for mounting tabs which can be removed from one to make the other.

I hope that helps!

@Idan-Fiksel let me know what we need I can get it.
