Some complete and work-in-progress pictures of the Airball probe "sensor board". This puts all the pressure sensors onto one modular unit with 4 signals going to it: power, ground, I2C clock, and I2C data. This way I can experiment with the "compute board" as I want to without risking damage to my expensive sensors: The stuff you see here is $200 worth of kit!
The soldering could be better as always since I'm a n00b but it wires up properly and works!
Now waiting for 3D printed probe parts to assemble the first functional probe and do a full system test.
