USB Interfaces

The conga-SMX8-X offers pins for five USB ports by default. The USB[1:4] pins are provided via a TI TUSB8041 USB 3.0 hub. USB0 is directly
routed to the SoC.
Optionally, the conga-SMX8-X can be offered without the USB hub and the USB signals from the SoC directly routed to the USB3 pins instead
(assembly option).
Optionally, the conga-SMX8-X can offer an onboard Wi-Fi/BT module instead of the USB4 pins.¹ For more information, see section 6.4 "Wi-Fi
