Hello, I've seen many people reporting Z-axis reading problems with the ADXL345 here and on other communities, but no solution nor explanation.

 

Could it be a deffective batch?

 

I have 4 breakout boards with the ADXL345, and two of them present the following problem:

 

If set to 16G scale, the Z-Axis readings change when the accelerometer is moved, but when set to 2G scale, the Z-Axis readings are stuck at the end of scale.

 

The two "good" chips are marked:

345B

#223

0736

and

 

345B

#224

7352

and the two bad ones are both

 

345B

#119

3748

Thanks,

Joao S Veiga
