Stratux AHRS 2.0 - Raspberry Pi Sensors and Fan Controller - ICM-20948+BMP280

Stratux AHRS 2.0 - Raspberry Pi Sensors and Fan Controller - ICM-20948+BMP280

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?

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

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+?

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?

No. It has a fan controller circuit and inertial sensors for AHRS (accelerometer/gyro/magnetometer), and a pressure sensor for pressure altitude.
