Hardware
4.2.13
PSoC 64 MCU USB Section
The board contains a micro-B USB connector for the PSoC 64 MCU. It is capable of both device and
host functionality. Although the PSoC 64 MCU does not support USB-OTG, the hardware is compli-
ant with it. By default, the PSoC 64 MCU device will work as a USB device; when an OTG cable (all
such cables have ID pin connected to GND) is connected, it will work as a USB Host.
As a USB Host, the board must provide power to a USB device that is connected to it. This power is
provided by VBUS_HOST which is controlled by the PSoC 64 MCU using a load switch. By default,
VBUS_HOST is powered using KP_VBUS and optionally can be powered using external sources
through
J10
.

Potentiometer Section
The board contains a 10K potentiometer connected to pin A6 (P10[6]) of Arduino-header (J2). The
fixed ends are connected to VDDA (VDD_POT through J25) and GND and hence may contribute to
leakage current on the P6_VDD power supply. Remove jumper J25 to disconnect power from the
potentiometer when measuring P6_VDD current.

Note: P6_VBUS will be powered using KP_VBUS and
hence will be limited in current based on other loads on
the kit. Please remove R106 and connect an external
power supply that supplies 5V @ 500mA for full USB
host functionality
