We are in need of [VOXL2 Ethernet expansion and USB Hub add-on](lhttps://www.modalai.com/products/m0062-2) to integrate with Flir Boson camera. We need data sheet of the product. In the technical docs page, it's not available.

Hi @Jetson-Nano 
That is considered a beta product in its current form and not broadly available, hence documentation is sparse/not available.

We have considered making an improved and current version of this design for public use, so if you have any feedback or suggestions/requirements, we'll gladly consider it for our future design efforts.
Thanks!

@Vinny Hey Vinny,

At the very least if you could tell us what connectors are on-board and which pheripherial are exposed [such as USB, UART, Ethernet port is seen] and where it is connected on the voxl 2 [like /dev/tthy4 ] it would be very helpful. Without these even making suggestions for improvements would be difficult.

HI @Jetson-Nano 
The board is similar to the M0090 5G Modem  board in the following ways:
- Plugs into VOXL 2 via J3&J5
- Exposes a UART+I2C JST and an SPI JST
- Uses the same USB hub, and exposes 3 USB Downstream ports, with one being a direct Type-A host port, the other 2 being our JST formats.

Where it is different from the 5G modem is we add a USB to ETH bridge, and expose a full RJ45 jack with Gb speeds (but limited to a USB2 backhaul)
We also have an SD/UFS card slot for memory expansion.
And we do not support the PCIe interface for modems... the RJ45 takes up that space.

I do not know how they enumerate with the OS, I am not on the SW team. Sorry I cannot help there.

Any of our USB expansion boards should work with VOXL 2 and Boson, you don't need this specific board
