Pauls personal autopilot project board....

[pbreed]

I have a small board based off of the Netburner MOD5213 it has

• Invensense MPU6000 IMU,
  A 3 axis magantometer HMC5883L
  A sensitive altimeter (MS5611-01BA03),
  RS 485,
  A socket for an XBee telemetry radio,
  Output drive for 8 RC servos,
  A 16M byte log storage chip
  4 Timer inputs that can read an RC reciever or 8 ch with a DIY Drones mux board.
  A few uncommited A/D inputs.
  an uncommitted serial port (probably used for GPS)
  The 485 and Xbee ports can be used if needed instead of their normal function.....
  It will run from 5 to 8V (expected to use 7.4V 2 cell Lipo)
  The CPU is an 80Mhz version of the 5213 with 256K flash and 32K of Ram

I built this for my own use and I have 10 working units at this time.
I've contemplated turning this into a product...
all the netburner MOD5213 tools work on this board...
I also believe 100% of the parts on the board are industrial temp...

You can see a picture of the board here http://www.rasdoc.com/pics/IMAG0101.jpg.

Would there be any interest in a board like this?

I would be interested.

I assume it would be good in a high power rocket. How big. How much. Im interested.

[pbreed]

I Don't know how much....
Depends on if I'm selling a few of the 10 I built or if we decide to produce somethign like this...

My cost to produce the 10 prototypes was about $125 each with zero pprofit...

As far as using in a HPR, I'll let you know on Monday this is flying in a 3 motor gimballed rocket guidance experiment on Saturday..

Here is the before and after pictures of the previous attempt...
(Failure was a motor burn through had nothing to do with the electronics...)

Did you launch it?

[pbreed]

Nope no launch this weekend...
On Friday night I connected a battery backwards and cooked my guidance servos....
(My electronics survived just fine.. the servos let out the magic smoke...)
I now have spares and the next launch is on Feb -2.

Hey Paul,

I am a member of the Cal Poly Space Systems club at Cal Poly at San Luis Obispo. We are currently building a guided rocket for Lockheed Martin and we would be very interested in having one of these.
