Hello community,
 I am working on VOXL2 with SDK 1.1.3 and for connecting radio Doodle labs I am using Microhard add-on board with USB connectors. I want to shift onto VOXL2 [USB3 UART expansion board](https://docs.modalai.com/voxl2-usb3-uart-add-on-datasheet/) but as I can see in its datasheet the JST 10 pin USB connector has multiple pins then just D+,D- and ground as that on USB 2.0 connectors on Microhard add-on board. Can someone guide me how can I map D+,D- and ground pins on 10 pin JST USB3 connector of this expansion board?

@Aaky you could use MCBL-00085 as a reference https://docs.modalai.com/cable-datasheets/#mcbl-00085
