Re: NavX Micro Case

The existing navX-Micro enclosure was designed for FTC use, this one seems like a better fit for FRC.

Ok if we put a link to this on the navX-Micro website?

Re: navX Micro I2C voltage and Roborio

In 2016, USB was not supported by the FRC WPI Library (there was a bug in the underlying RoboRIO support). This particular bug has been resolved in the 2017 firmware which will be released on...

Re: navX Micro I2C voltage and Roborio

The navX-Micro can be powered successfully even with 3.3V on the "5V" pin on the I2C connector, as long as it's really 3.3V.

The processor runs down to 1.7V, and the MPU-9250 runs down to 2.4V.

Re: [FRC Blog] 2017 Motor (and Servo?) Controllers and MXP

Yes, just to be clear, navX-Micro is definitely legal.

Rather than connect to the MXP port, NavX-Micro connects via USB and I2C and is software compatible with the NavX-MXP libraries. So it's a...

Re: [FRC Blog] FIRST Choice 2017

Full disclosure: As founder of Kauai Labs, I'm biased towards the navX-Micro so you should take this w/a grain of salt - but I wanted to toss out a couple of system-level considerations.

Re: Rev More Board and Nav-X

Also, the navX-Micro (http://pdocs.kauailabs.com/navx-micro/) is a lower-cost version of the navX-MXP which leaves off the MXP IO Expansion. navX-Micro also connects via USB (or I2C) - so that's...

V2 and V3 navX-MXP have the same hardware; firmware is the difference.

Re: NAVX vs. Spartan board

As creator of the navX-MXP/MICRO I have to say that the Spartan connector breakout is very nicely done - kudos to WCP on that.

Moving beyond the side-by-side gyro accuracy comparisons which I...
