From Kamamilabs.com - Wiki
Description
KAmodMC3635 is a module with the MC3635 three-axis accelerometer from mCube. The sensor allows the measurement of acceleration in the range of ±2g/±4g/±8g/±12g/±16g, the measurement frequency is from 14 to 1300 Hz. Communication with the sensor is realized via the I2C interface. The board is equipped with the Pmod I2C standard connector and the KAMAMI connector, that allows to easy connection of the module to the evaluation kits. Due to its small dimensions, the product can be used in many development projects, while the Pmod loop connector allows to connect the boards in the series.

I2C bus lines
The KAmodMC3635 module is equipped with jumpers allowing to connect pull-up resistors to the positive power pole to the I2C bus line. The jumpers give the possibility of independent enabled of the pull-up for the SDA and SCL lines.
Interrupt line INTN
The KAmodMC3635 module has been equipped with a jumper enabling connection of the INTN interrupt output line to the Pmod compatible connector. Thanks to the possibility of disconnecting the MC3635 interrupt line from Pmod connectors, the user does not have to worry about the consequences of possible conflicts resulting from the connection of Pmod-compatible module modules with different logic states.
I2C address
The KAmodMC3635 module has been equipped with the function of selecting one of the two I2C bus addresses for the MC3635 chip. The jumper "Addr. 0x" in position "4C" causes that the integrated circuit will be represented by bus address 0x4C (HEX), and in position "6D" - 0x6D (HEX).
