WebbThe I2C bus needs pullup resistors to work. A normal value is 4k7. Sometimes there are already 10k pullup resistors on a sensor module. If the I2C has problems, start by using short seperate wires for SDA and SCL. When a cable is used for the I2C bus, then the cable is probably the problem and not the pullup resistors.
