  • Please answer this question.

  • The tolerance for the zero, and scaling of this chip is very loose. You will have to do what is called a 3-Point calibration. Take one reading at -1g’s one reading at 0-g’s and one reading at +1g’s then use those three points to find the slope (scaling factor mV/g) and offset (0g point). y=mx+b

  • Caught this same thing. The Output impedance is 32K which is quite high.

    Definitely agree about adding the buffer / follower.

    Sparkfun please address this, otherwise you are going to have a whole bunch of very frustrated novices not getting accurate values on their arduinos.

  • Expensive, but damn it is worth every penny. Highly recommended.

  • +1 I also need to know this.

  • Wow! Just finished reading the data sheet. This is a bad a@@ chip. I can’t wait until I get to a point where I would need something with all the features this chip has to offer.

  • Sparkfun,
    Thank you for making such great quality perf boards and thank you for including MOUNTING HOLES!!
    AHHHHHH!
    Sorry, I just really love mounting holes
    Cheers

  • SparkFun is currently sold out of their Micro SD Cards and I am looking for one that will work with this logger.
    What Interface standard should I be looking for?

  • Will the charger only charge single LiPo 3.7V cells or can it also charge 2 cells in series (7.4V)?

  • Heads up, the clocks on these vary by a few percent, so if you are going to gang up multiple loggers the data will be a little out of sync. Mine were off about 2.7%

No public wish lists :(
