what kind of differences are between ADXL343 and ADXL345,
except samplerates below 6.25Hz for ADXL343?
In Selection Table (the link is here: Selection Table for MEMS Accelerometers )
Bandwidth -3dB for ADXL345 is 1.6kHz and only 0.32kHz for ADXL343
But it seems 0.32kHz for ADXL343 to be mistake,
cause in the Datatsheet the highest samplerate for ADXL343 is 3200Hz and appropriate bandwidth 1600Hz
