  • Hello, I have 4 of these sensor boards and tryed to multiplex between these four with a 4052 analog multiplexer. The gyro and accelerometer give response, but not the magnetometer. It seems like the 4,7kohm pull up on the sensor boards in combination with the 4052 gives to high resistance so the magnetometer could not process the i2c signal. If I use the same code and same schematic by just replacing the multiplexed lines from the 4052 with some hardwired multiplexing on its socket everything works with the magnetometer,too.

    Has somebody an idea, how I could solve the problem?

No public wish lists :(
