Is 2:22AM (when i started writing this) and i can't sleep, so i decided to write this post.

I been working "hard" and the fastest i can to finish this thing, theres only one step remaining in order to start the "mass" production of this board.

This is how the last step will be done:
-A unique assembled board will be shipped from California to Spain.
-Then Jose Julio in Spain will open his "Surprise Board" and make us the great favor to all of us of checking the board integrity and the harmony of all the components on it (thanks in advance JJ).
-That includes checking some new components i can't mention right now.
-If Jose Julio says 'Si", then i will start the mass production.

By now SparkFun is straggling trying to supply all the components and test bed for APM. It will be released soon.

The board is kinda of big right now. This board will be called the "huge" version. When the code becomes very mature i will create a an smaller version of the APM and APM Oil Pan without the multiplexor on the APM and without the bulky FTDI chip on the APM Oil Pan, so i can save 30% of the size. This one will be called ArduPilotMega "In my way" version. ;-)

Oil pan stands for the old shield name. The difference is that the shield goes into the bottom of the ArduPilotMega board.

I decided to let the community guess the rest of the specs for ArduPilotMega Oil Pan, because write stuff in English make me drowsy. The best guesser will receive a $50 certificate. ;-)

Come 2:56AM!!

Hi Jordi,

very nice idea.

Does it go further with UDB Oilpan too ?

Best regards,

I can see it has a microphone, probably for accepting voice commands. Pretty slick Jordi, now we'll be able to shout at our UAS from the ground and have it respond!

Just to translate for those who may be confused: "APM" = ArduPilot Mega. "Oil Pan" = Jordi's code name for the ArduPilot Mega shield, which included the IMU and other sensors, along with the USB port.

Hi Jordi,

Nice board! As you said quite big…

Here my guess for the oil pan:
-FTDI chip (top-left)
-Multiplexor (bottom-left)
-Differential Pressure Sensor MPXV5004DP (top-right)
-Gyro LPR530AL for Pitch and Roll (center)
-Gyro LPY530AL for yaw (center)
-adxl335 accelerometer (bottom-center)
-Analog to digital (SPI) converter (right of Gyros)
-Probably an SPI Magnetometer (right of Analog converter)
-Reset or home PB (right)
-GPS Connector (bottom-right)
-Serial port connector (top-left)
-Some led’s.
-Power regulator (left)
-Data logger port and voltage lever converter (bottom-left)

I didn’t saw Chris Anderson comment, but with his clue what is in the bottom left is the USB port.

Note that the size of this shield is determined not so much by its own components but by the Ardupilot mainboard, which it fits on. And that's big because it's using the Atmega1280, which has a TON of I/O! There's a reason it's called "mega" ;-)

BTW, it's not as big as you may think. Here it is between the current ArduPilot board, which is the smallest on the market, and the UAVDevBoard:

I may be late to the game, but here's my guess

May be this might help you guys , cheers :))

I2C external port lower right, USB mini upper left, analog temps input lower left, Current sensor center left, I2C compass port center (Charlie 1), 4 option switches lower left, IMU in center, SPI to ADC center top right, air pressure sensor top right.

Ok everybody is so close, but still missing a couple of parts, i will say no to the wrong guesses:

-No a microphone Curtis, hehe

-no Multiplexor (bottom-left)
-Yes and no a Probability of an SPI Magnetometer (right of Analog converter)
-no GPS Connector (bottom-right) because is already on the main board
-Serial port connector (top-left)?? Yes it has four serial connectors.

-analog temps input lower left, Excuse me??? temps?
-No Current sensor center left
- I2C compass port center (Charlie 1), close but is not for the compass. The compass will be external for interference reasons.

-One of the missing components was used by Sparkfun in a rocket.
-The rest of the missing components are already on my store, populated in other boards.
-The rest are switches of different kinds...

The person that list me all the active components (at least), will win, extra points for passive components guesses.
