Dual USB HOST Connector4.5. Micro-B USB Device Connector (J34)The MCIMX53SMD board has one micro-B USB device connector that can be used to connect theMCIMX53SMD board to a USB Host computer. The micro-B connector is connected to the high-speed (HS) USB2.0 OTG module of the i.MX53 processor. When a 5V supply is provided to the micro-B connector (from theUSB Host), then, the i.MX53 processor will configure the OTG module for device mode. This will prevent thelower USB Host port from operating correctly. The 5V power provided by the attached USB Host is only usedby the i.MX53 processor for sensing that the host is present. The MCIMX53SMD board will not draw powerfrom the connected USB Host and will not operate without a 5V DC power source or charged Li-ION battery.The micro-B connector is keyed and will not accept a micro-A plug from a cable. A micro-B to USB-A cable issupplied as part of the MCIMX53SMD board kit and can be inserted into the micro-B USB connector at thepoint shown in Figure 4-5.Dual USB HOST Connector (J31, J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)Dual USB HOST Connector (J31,J32)
