    Please answer this question.

  • Product SEN-09652 | last year

    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.

  • Product COM-08429 | about 3 years ago

    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

  • Product WIG-10216 | about 3 years ago

    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?

  • Product WIG-10216 | about 3 years ago

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

  • Product WIG-09228 | about 3 years ago

    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 :(
