Figure 14 shows the USB interface schematic.
Figure 14 USB Interface Schematic
4.5 Arduino-Compatible Expansion Headers
The S5D9 MCU board includes Arduino-compatible headers that enable interfacing with a wide range of Arduino
Shields and expanding its features. Most of the interface signals are connected directly to the MCU pins. This enables
their configuration to change depending on the application needs. Figure 15 indicates the port and pin number for each
interface signal along with its primary role. The specific function and pin-muxing depends on the application and the
hardware specifics of the S5D9 MCU.
Note that the 5V power brought to the POWER header pin 4 is connected directly to the USB VBUS power rail from
the USB device connector (J6).
