Hi Felix,
I wonder why you put 10uF in // with a 100pF on VDD of the BMP 180 while the data sheet of the BMP180 only recommend 100pF ? Pretty sure I miss something here
Thanks,
Valery

It's because caps should be as close to the chips as possible, a 10uF should reduce any ripple comming through the headers to the shield.
