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.

Note that the Base Board includes 2.2kΩ pull-ups for the I

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.
