USB Interfaces
The PandaBoard utilizes two USB interfaces. The first is a DP/DM interface from the internal transceiver
within OMAP to the mini-AB connector J18. The second interface utilizes the 12-wire ULPI interface
(USBB1) to an onboard USB phy, whose DP/DM I/Os are interfaced to a Hub IC which provides four
downstream USB Host ports, and an Ethernet interface. Each of these interfaces will be discussed in
more detail in the following paragraphs.
2.15.1 USBOTG Interface
The PandaBoard uses the USB OTG transceiver within the OMAP4430 that is connected to an industry-
standard mini-AB connector (J18) as shown in Figure 15. The VBUS from the connector is connected to
the TWL6030 companion Power IC, which can provide up to 100mA in host mode. The PandaBoard
may only be used in host mode if a +5Vdc power supply is installed in power jack P2.
