[Paparazzi-devel] apogee board 2.0 - feature questions

we have decided to update apogee board due to discontinuation in
production of some parts. I would like to know the opinion of the
interested paparazzi developers on the changes:

- IMU will be updated with MPU9250. This will eliminate need for an
  external magnetometer

- SD card sold is discontinued, and will be replaced by the one
  currently in production by molex

- mounting holes - we find the 1.8mm holes pretty difficult for
  mounting the board. The holes will be changed to 2.5mm

- servo connectors - we would like to turn the 3 pin connectors 180
  degrees, so that pin 1 corresponds with servos signal. This will make
  the board consistent with the standard molex 1.25->futaba/JR harness

- power connector - we find the power connection to the board a bit
  difficult without a proper connector. The 4mm connectors (the distance
  between the 2 pads) are rather too big for such a tiny board. We will
  place a 4 pin 1.25mm molex blade header - pins 1,2 as Vdd+, and pins
  3,4 as GND. This will still leave the option to solder wires directly
  to the board.

Any other objections regarding the board update are very welcome.

Best regards,
