"On the same wiring diagram you connect several sensors on the same GPIO pin, how do you actually connections?"
I want to make a clean connection, without soldering if possible.
I take an old ide ribbon cabel (with 40 pin idc header) and put on some 25 d-sub idc. I cut an old centronix printer cable and put the wire into a box (be sure to disconnect the old ground bridge from pin 18, 19, 20, 21, 22, 23, 24, 25 of the 25 sub-d) . You can solder the 4 i2c cable to
the BMP180 shield or connect it via a crimped 4-pin Dupont head.![[Image: lightbulb.png]](http://forum.openmarine.net/images/smilies/lightbulb.png)
On the next 25 d-sub you can connect annother i2c shield. You can also make a box connected to the d-sub 25 for One-Wire DS18B20 (but don't forget the 4.7 kOhm resistance).
