26 G30 - Module Hardware Description December 15, 2009
It is recommended to implement the above in accordance with the following table:
Note: Recommended application connector: SAMTEC TSM-106-02-S-DV-LC 12 pin.
I
2
C Bus Interface
The module provides an I
2
C bus interface which includes a serial data line and a clock line on the
board to board pins. The G30 I
2
C acts as master only. The I
2
C bus interface is available to the
user only with M2M Zone Platform.
The I
2
C signals are pulled-up, using internal 4.7 kOhm resistors.
Note: Do not connect any pull-up resistors when using signals as I
2
C interface.
Note: The I
2
C Bus interface can only be activated by M2M Zone Platform. Otherwise, the I
2
C
signals are configured as GPIOs.
