33 mm? So this is real small? Looking at the pictures, I had expected something the size of a Honeywell T87 thermostat.

And why the “3-axis accelerometer and 3-axis gyroscope”? Is it meant for mobile applications, so put it on a drone or bicycle?

Looks nice, but without wireless communication i can’t think of much use for it.
