Hi Gautier

A cut and past of a reply to an order I placed with Droneasy on or around Sept 2013 -

Thank you for your order. There are 9 DOF and 6 DOF IMU version. Which version do you need?
6 or 9 DOF IMU
Apogee v1.00 PCB offer two Invensense IMU chip options:
MPU-6050 : 6 DOF, 3 axis Accelerometer + 3 axis Gyroscope
MPU-9150 : 9 DOF, 3 axis Accelerometer + 3 axis Gyroscope + 3 axis Magnetometer

I chose 9 DOF option and bench tested using ENAC's airframe with external Mag.
Seemed OK - but it has yet to fly.

As Andreas said, the Apogee board is not obsolete at all and we are
using it in all our airframes at Enac. Unfortunately, since PPZUAV
stopped his business for an undefined period, it is a bit difficult to
find suppliers.
I'm glad to see someone is manufacturing them again. We are also looking
for some other suppliers to make it more easily available.
Andreas, do you know from which country droneasy is ? Are they shipping
worldwide ?

I order the boards even if they are on backorder (I guess they are just
produced when there is an order) but it takes only around 4 weeks from
the order placement until it has arrived to Europe (including some
visits at the customs). The quality seems good (in contrast to some
former discussions). I just had one out of 6 boards which did not work
properly, but it was no problem to send it back and get a replacement
(paid one shipping direction).

In my opinion this board is by far not obsolete but extremely useful (at
least for meteorological measurements) since it brings the sd-card and
logging function onboard (easy to write, easy to read). You just have to
decide between 9dof and 6dof imu. I unfortunately used to order the
former ones (9dof), but now cannot use the barometer since the I2C
adress changed (something Gautier fixed already but I got it to work
only for multicopters not for fixedwing airframes and it is not yet
included in the master branch). Thus, if you want to use the barometer
easily order the 6dof imu (Gautier also said the magnetometer is not
very precise, if I remember correctly). But all in all I'm very happy
with this board!

Hope that helps,

I am interested in getting one/few of the Apogee boards for testing. I
have researched all the relevant links from the wiki, none of the listed
companies have this board in stock. Everything is on backorder. Is the
board already considered obsolete? If so, why?
Is there possible somebody in the list devel list who
can sell one of his assembled boards, please let me know.

Best regards,
