• ### New product: LPS25H pressure/altitude sensor carrier

- 26 November 2014

Hi, Jeff.

The data for this comparison was taken with a sampling rate of 12.5 Hz for both sensors and all other settings left at their power-on defaults (except for additionally enabling the hardware moving average for some tests); see the enableDefault() function here:

• ### Continuous-rotation servos and multi-turn servos

- 9 August 2012

Hi, David.

We don't know of any specific considerations with digital servos, but I think it's going to depend on the particular model of servo, and we haven't tried modifying that one. You should get a pretty good idea of whether it will be practical as soon as you open it up.
