The accelerometer and the magnetometer have separate 7-bit slave addresses on the I2C bus. The magnetometer’s slave address is 0011110b and cannot be changed. The accelerometer’s slave address has its least significant bit (LSb) determined by the voltage on the slave address selector pad (SA0_A). The carrier board pulls SA0_A to ground through a 4.7kΩ resistor, setting the accelerometer’s slave address to 0011000b by default. If the accelerometer’s selected slave address happens to conflict with some other device on your I2C bus, it is possible to access SA0_A through the untented via on the bottom of the board and pull it up. In our tests of the board, we were able to communicate with the chip at clock frequencies up to 400 kHz.

}
wenn ich die Adresse 0011110b einsetze giebt es einen fehler wegen dem B.
und was muss ich für einen Wert senden?

Bin ich Blind?
