I was about to order one from digikey, so I can't help you with your question yet, but I was hoping you could help answer mine.
The datasheet calls it a PLCC-20 footprint, with 0.5mm spacing between pin centers. However, every PLCC-20 adapter I could find seems to think the standard is 0.05", aka 1.27mm.
Am I confused about PLCC, or is the honeywell datasheet incorrect? (or some awesome combo of both) I guess I can order the chip then make a custom PCB for it, but I was curious what you used to mount and test it, since you're obviously getting an i2c signal in and out.
