    This can be increased to the typical 120uF minimum required by the USB specifications for dedicated host devices if OTG mode is not required. On the PHYTEC Carrier Board, by default the USB0 port is configured as OTG, including having under 6.5uF capacitance on VBUS. It can be configured as a dedicated host instead by installing jumper JP10, to add 150uF additional capacitance to VBUS, and installing jumper JP12, to pull the ID signal low.

    On the PHYTEC Carrier Board, the SPI0 interface connects to the GPIO Expansion Module and also to the LCD connector. The LCD connector is also on the SPI0_CS0 signal. If the LCD on the Carrier Board requires SPI, then the SPI Flash on the SOM should be disabled using SOM jumper J3.

    The GPIO Expansion Connectors at X5 on the Carrier Board provide access to many of the phyCORE-AM335x SOM signals. As an accessory, a GPIO Expansion Board (part # PCM-957) is made available through PHYTEC to connect to the X5 GPIO Expansion Connectors. This Expansion Board provides a patch field for easy access to all of the signals and additional board space for testing and prototyping.
