Hi Urs, thanks a lot for your help. I tried to deactive all integrated sensors in my MDA300CA sensorboard with MicaBusC component; I used "clr()" in Int0 - Int3 and PW0 - PW7, but the current is always about 5 mA. I would like to disconnect the power to the sensorboard, but is it not possible, right? My app reads ADC values by the sensorboard each three seconds, but my sensorboard consumes always 5 mA. In this case the battery life is too short. :( Does it exist another way to deactive the current?
Thanks again for your time.
