User Guide Rev. 1.0
Function
Switch for connecting either periphery like e.g. the
GPIO header pins or USB related pull resistors to the
native USB traces.
3.11 USB-IO Switch
Is connected to the PAN9520's RF pad.
3.15 PAN9520 RF Switch (SPDT) Control
Pin header to swap the Arduino interface's pins for
UART TX and RX signals.
3.9 Arduino Board/Shield Configuration
For entering the application Boot Mode per default,
when powering the module, the pull-up on GPIO0
must be connected.
3.4 Default Boot Mode
Pin header for connecting UART0 (TX and RX),
RSTn (DTR controlled), and IO0 (RTS controlled) of
the module to FT2232.
Pin header for connecting the module's UART1
signals (TX, RX, CTS, RTS) to FT232.
4.7 kΩ pull-up resistors can be connected to GPIO 7
and GPIO 8 via these pins. GPIO 7 and GPIO 8 are
used for I²C (Inter Integrated Circuit) on the Arduino
socket and camera connector.
3.12 I²C Pull-Up Resistors
Low supply voltage control of camera interface. 1.2,
1.5 and 1.8 V can be configured by several jumper
settings.
3.13.2.1 1V2-1V8 Pin Header
High supply voltage control of camera interface.
2.8 V, 3 V, and 3.3 V can be configured by several
jumper settings.
3.13.2.2 2V8-3V3 Pin Header
Connector for using different camera modules.
3.13 Camera Interface
USB to serial IC that is used for interfacing UART1
(inclusive flow control).
