Superbly informative manual! I haven't seen any instruction manuals for commercial rocketry electronics that go into anywhere near as much detail as you have done with this.

Here's my take on it It's designed to mount horizontally in a stack of boards, so I had to put the ADXL78 on a sub-board and solder it at right angles to the main board. PK

Looks good.
What's with the resonator ?

Yep running of the internal 16MHz oscillator and x4 PLL.
Figured accuracy may be fraction lower but is more robust and get a few more I/O.
Will still work with resonator in place I guess.

That is one serious looking array processor.  It would be interesting to see them flown in pairs to see how much the recorded data varies between the different boards.

Nice job. Looks good. I assume this will be a commercial product?

A narrower version (24mm wide) of the FC for Andrew's micro hybrid rocket. Placed next to PK's micro mad for size comparison : Attachment:

Not much time to get it going but should manage it. Would be nice to get some data from his flight. CS
