Hi guys,

I've been hard at work making a small, single board hardware platform for stabilization/autopilot purposes.

 

The board is very small.  Currently it measures 1.5"x1.1" (39mm x 28mm).   It runs a 16Mhz Atmel Atmega328p.

Also, included on board are a 3-axis mems gyro, 3-axis mems accelerometer and a 3-axis magnetometer (no in the picture above).

 

Input voltages are 5v-16v. 

The board can see use up to 16 I/O ports for PWM (in/out), external modules etc...

There's also a I2C header for external I2C units.

 

The alpha boards are already running a cut-down DCM code:

 

I'm planning to implement fist a version of the Ardupirates code.

If you're interested in one of these please drop me a line here or via email (erezraviv@gmail.com)

    The price is $95 for the magnetoless version and $120 for the magnetometer enabled version:

    The Ardu variants are based on Arduino. In my experience the programs tend to be a little hefty. I haven't completed the port so I can't say yet but most of the functionality should be available.

    Given that the Atmega328 has 1/4 the memory of APM's Atmega1280, how do you intend to squeeze the ArduCopter/ArduPirates code in there?

    hi, very cool , any idea of the price ?

    Thanks!
    I think the advantages are not just the small size.

    The sensors are integrated 3-axis mems sensors. That way they are very orthogonal. The communication with them is digital and not analogue so voltage variations do not drift them.

    I think the biggest advantage is having it all in one board and not having to cobble together stuff from SF/Wii/HK gyros etc...

    very pretty board.  of course you need to put it into a very small quad (or whatever) to show off the advantage of the small size (which of course will come at the expense of some features).
