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.
Come 2:56AM!!
Comments
Here are the parts that I could identify:
- FT245RL (top left)
- PCA9306 (Converts the 5V I2C signals to 3.3V for Jordi's SCP1000 board)
- LY530ALH (near the ADC)
- LPR530AL (near the ADC)
- ADXL335 (near the ADC)
- MAX147 (tssop-20 or ssop-20 package)
- AT45DB161B (right of the ADC, soic-8)
- MPXV5004DP (funky freescale package)
- BM06B-SRSS-TB (the connector on the bottom right)
- 3.3V Regulator (SC70-5 or SOT-23-5)
- Dip Switches (bottom left)
- RC Filters for the ATMega1280 ADC inputs (bottom left)
- Mini USB connector (top left)
- LEDs and their resistors (left of push button)
- Switch (on the bottom right edge)
- Generic caps for filtering and resistors
But I can't figure out what the package on the left is. It looks like it could be a solid state power switch, or a current sensor. I can recall seeing that package before, but I don't know where. There is a single non-power trace going from the package to the T5 (clock input) of the ATMega1280 on the Ardupilot Mega board. So it either gives a PWM output of some sort which is measured by the AVR, or it was arbitrarily assigned to that pin (less likely).
Ops sorry i got lost, can you remake your "correct" list please?
-Jumpers (bottom-left) to monitor outputs, no multiplexor… Can you explain more about this... pls?
-No infrared sensors XYZ Horizon connector (bottom-right)
-I2C conector for pressure sensor (SCP1000) or magnetometer (HMC5843) (bottom), more details please.
-The left “strange” pads could serve to ppm encoder in order to monitor some radio inputs (flight mode). mhhh noup...

Sorry if mismatch but I don’t have APM board to check.

Your picture example is correct. the problem was the pressure sensor is huge, so i decided to put it "externally", also the LED's and the push button are outside for easy access.
-No optocoupler or power MOSFET
You have a couple of weeks to guess out.. ;-)
Another pic:
-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.
Hints:
-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.
