We are planning a 7-port USB 2.0 hub for VOXL 2, connected through J3, using the Microchip USB2517. We wanted to use this to connect more sensors and USB cameras to the VOXL 2 board.

I’m following the USB expansion guidance in the VOXL 2 Expansion Design Guide and wanted to ask:

• Do you have a reference schematic for a USB 2.0 hub connected to J3 that you could share?
• The guide mentions that ModalAI may review customer expansion-board designs. Once I have my schematic ready, would you be willing to review it before I proceed to PCB layout?

Thank you in advance!
