SP7: USB Interfaces 

The 

iMX OEM Carrier board

 has two USB interfaces, one USB Host and one USB OTG: 

 

The USB Host interface has a USB-A connector, J13. By default this interface has VBUS 

power enable always on. LED8 indicates the presence of +5V VBUS for the interface. This 
USB interface is connected to i.MX RT1052 USB interface #2.  

 

The USB OTG interface has a micro-AB connector, J12. By default this interface has VBUS 

control via the ID-pin. This USB interface is connected to i.MX RT1052 USB interface #1. 

o

 

If no cable is inserted or when a cable with ID pin floating is inserted, VBUS will not 
be powered on the J12 connector. 

o

 

If a cable with the ID pin grounded is inserted VBUS will be turned on, i.e., powered 

with 5V. This is the typical situation when connecting a mini-AB to USB-A USB 

cable, i.e., when wanting the USB OTG interface to behave like a USB Host that can 

possible also power an external device via VBUS. 

See picture below for locating relevant components..
