Hi,
here a brief status update:

* components have all arrived, except one
* the one is a new one which IMHO compensates for waiting some more days!

Thanks to generous support by Bosch Sensortec we got an option to buy the
BNO055 intelligent 9-axis Absolute Orientation Sensor, which includes sensors
and sensor fusion in a single package. It combines an accelerometer (position),
gyroscope (rotation speed) and compass (absolute position) and a microcontroller
in a single package. All data can be read through I2C.

So this means we directly get the orientation data e.g. for Replicant games and
augmented reality (which needs a working camera...) right from this chip and do
not need to run complex algorithms on our own.

This chip will be installed in addition to the BMC150 and BMG160 (because we
already have bought them). And, the BME280.

We have already tested this chip on a Pyra handheld prototype mainboard which
also has place for it and we have got someone who has written a first kernel driver:

It is not perfect yet, but shows that the sensor will work.

All this mens that thanks to Bosch support, we will very soon have a very modern
orientation sensor in our open smartphone platform.

BR,
Nikolaus
