This connector shares SPI interface signal connections with the Arduino expansion 
connector J9. 

The I

C interface signal connections used for this connector are shared with the Arduino 

expansion connector J9, and are also connected to the accelerometer and the touch 
screen controller.

signals. 

6.5  Arduino UNO expansion connectors 

The OM40006 board includes four expansion connectors (J9-J12) compatible with 
Arduino UNO revision 3. These connectors provide access to I

2

C, USART, SPI and 

several GPIO/INT/PWM connections. Note that several of the signals available at these 
connectors are shared with other connectors or board functions, so might not be usable if 
those other functions are being used by other devices. 

Table 5 below shows the connector circuit references and purposes.

Description 

J9 

Arduino Uno rev3 Digital 15:8, AREF, SDA & SCL connector. Also includes 
two interrupt / PWM connections. 

J11 

Arduino Uno rev3 Digital 7:0. Includes 6 interrupt/GPIO/PWM signals and 
USART interface. 

J10 

The even numbered pins 6 

– 20 are compatible with the Arduino Uno rev3 

Power connector standard.   

J12 

Arduino Uno rev3 Analog connector.  Provides 3 ADC connections plus 3 
GPIO/interrupt signals. 

Below shows the sharing of signals between the expansion connectors and other 
connectors or circuit functions. Refer to the board schematics for more details.
