Review: Great addition to the Stratux kit! - It works quite well, but is dependent on Stratus 1.3 or later for AHARS to work. If you try to install it in a Summit case, it won't fit without modification to the case. The fan will need to be placed on the outside of the case and the antenna mounts will have to be moved underneath the Raspberry Pi (new holes will have to be drilled). With the onboard barometer and a pressurized airplane, the traffic altitude is distorted because it's sensing pressure altitude and not true or GPS altitude. I have figured out how to fix this yet. Also, when the fan is connected to the Fan Controller, it will take 10-15 seconds to spool up while the system boots up.
Review: Works perfectly! (Also in Foreflight if the correct image is built) - I bought my first one back five months ago, it's 40 flt hrs later and I love it! Built a second one as a backup and it works perfectly. I use Foreflight and the AHRS works on the SD card I built back in August. Most current Stratux image shows ahars working in GPS/AHRS menu tab. I had to go to settings and add a .sh file with the gray "Click to select System Update file" to get Foreflight to see the Stratus AHRS and not get the "No Attitude Information" message in Foreflight. I can't find and don't remember the .sh I used to make foreflight to accept the Stratux AHRS. Foreflight customer service assured me that they do no block features from any devices. I updated my Stratux and it worked. Now to find that file to make a spare...

## Questions & Answers

**Q: Could this chip possibly be built with the bosch bme280 chip instead and then potentialy add a density altitude calculation if software is modified?**
A: I've developed most of the AHRS code for Stratux.  The problem with calculating density altitude is that the temperature in a Stratux case is dominated by the other electronics, especially the SDR boards.  Even if that weren't the case, the cabin temperature can be quite a bit warmer (or cooler with A/C) than the outside air temperature.  So measuring the temperature, or even humidity, with a BMP280 or BME280 in the typical Stratux installation would not give good results for a density altitude calculation.  The sensors would have to be placed outside the aircraft for this purpose.

**Q: Bought pre-built stratux from amazon and ahrs works with foreflight . now i built one , used this ahrs component and i have no synthetic on foreflight**
A: Foreflight is, unfortunately, tied directly to Stratus and doesn't like competitors.  As such, their code is tweaked in such a manner as to try and block this functionality.  To get it back, simply search for Stratux Dangerzone in google and then download the appropriate Dangerzone update build from there.  It is based off of the Stratux builds but found a way to get around Foreflights attempt to block AHRS. It'll be an update .SH file so you should be able to use the update function in the Stratux Settings page to upload it once downloaded.

**Q: Will this work with a PI 3 b+?**
A: It will work with any Raspberry Pi with 40 pin GPIO headers. Will probably also work with 20 pin headers too.

**Q: Is this just a fan controller?**
A: No. It has a fan controller circuit and inertial sensors for AHRS (accelerometer/gyro/magnetometer), and a pressure sensor for pressure altitude.

### ⭐⭐⭐⭐⭐ First one non-functional... with a new replacement that works perfectly.
*by L***N on October 29, 2018*

Update- these guys stand behind their products and reputation. They shipped me out a replacement chipset which worked flawlessly right out if the box. Thanks, guys. Will buy more Stratux stuff from you as new stuff comes out! Cheers! The first one I received was non-functional. I reimaged the SD card on the Pi 3 and reloaded in, rebooted, no joy. No attitude data on the Stratux page in my browser or on the iPad running ForeFlight. Both showed the AHRS as being present and recognized, but absolutely no response to changes in roll/pitch no matter what I tried. Returned for a new one. I will update after I receive a good working module. UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE UPDATE I received a new module via UPS before the one I returned had even left my mailbox! Great service. In about the time it takes to type this update I had installed the new one and booted it up, loaded ForeFlight, and I now have a 100% functional Stratux with GPS, AHRS, ADS-B in dual channel, and can't wait for this overcast layer to burn off so I can go fly!
