I just found an app note from Honeywell which states that pin 5 should be connected to VDDIO rather than the no-connect listed in the data sheet. They say it will affect I2C performance in a small percentage of parts if left unconnected. I’m having some I2C hiccups on mine, so I’m going to try adding a jumper.
If there is an opportunity for a design rev of the breakout, adding the pin 5 connection would be good change. As of April 2016, Honeywell has listed this chip as end-of-life, so it seems doubtful that this design will be around too much longer…
No public wish lists :(
