RB5 Ethernet Add-on

[joshuagaus]

In the RB5 documentation a "Gigabit Ethernet add-on with USB 3.1 Hub" is listed as an "Optional Expansion Add-On" along with the 5G modem and an SD card expansion. https://docs.modalai.com/Qualcomm-Flight-RB5-functional-description/

Is this currently available? I cannot find reference to it anywhere else.
I would like to integrate a third party radio with an Ethernet interface (Doodle labs RM-2450) with the RB5.

Thanks

You can just use a USB to Ethernet dongle. Our Doodle Labs integration guide is here https://docs.modalai.com/doodle-labs-user-guide/

Chad,

Thanks for pointing me in the right direction.

2 Follow on questions:

• for the RB5 specifically, do you suggest using the main usb-c port, or the modem carrier board J12 usb connector, or do I need to replace the modem carrier board with the VOXL USB Expansion?

• Is there a pinout for the modem carrier board on the RB5, as opposed to the main 'flight carrier board'? I only know that the J12 modem carrier connector is a usb connection because of this photo on the functional description page: https://docs.modalai.com/images/datasheet/RB5/rb5-labeled-2.png

@joshuagaus You would use the 4 pin JST USB port on the modem carrier board.
