The Eagletree Airspeed module is VCC +5V (And subsequently the i2c levels I suppose)Lisas i2c(2) port is +3.3 volt though.Has anyone done this before? Does the ETS module perhaps run on +3.3V? Or do I need to buy a level converter? Any tips which chip I should use? (nice and small SOIC package with few external parts so I can do dead bug style construction on the connector)
Oh well, that one was easy. If I need a level converter, the TI PCA9306DCTR seems to do the trick nicely. Just needs two pullups and a filter cap.
Will I need to do this?
