Do you want an ArduPilotMega board? (Limited)

I know some of you want to help and also for those that can't wait to put their hand's on the ArduPilotMega board here is your opportunity: You can be a Beta tester!

The final version of the board will almost the same, just some small corrections like an extra set of resistors pads i added just in case that will be removed in the final version, right now are just bypassed.

The requirements for being a beta tester are:
-Have and know how to use an AVR ISCP Programmer (i recommend the AVRISP MKII), to upload new HEX's just in case we decide to change the PPM encoder firmware.
-Windows XP/Vista/7.
-Have a FTDI cable programmer.
-Know how to use Arduino Environment and some basic programming skills.
-Have a clue what digital electronics means (If you are a regular user or a certified noob, i don't recommend this board to you right now).
-Willing to share your experience!
-Have $38.90 dlls $44.90, i'm giving the board almost to the production cost (for low quantity's). The final version may cost up to $65 dlls!

If you are ok with all this, you are welcome to get one board right now:

The boards come with firmware (for AT328) and bootloader (for AT1280).

I will be posting news&updates on the comments.

I have a basic firmware that reads and decodes the PPM signal and display the 8ch PWM's into the terminal:

The folder "PPM_Decoder_AT1280" is located the code for Arduino IDE. On the folder "PPM_Enconder_AT328" is the firmware for the PPM enconder, if you have Windows and the AVRISP MKII just double click on the .bat file and press any key and it will upload the hex to the board, make sure to connect your programmer on the "AT328 port".

PPM Encoder configuration:
-MUX is controlled by input CH5.
-Throttle FailSafe is input CH3 (Futaba).

The Eagle Files of the Board are here:

It looks like you are already out of boards (QTY=0 on the Store webpage) but I wondered what we can do without the IMU shield anyway. Also, is the airspeed pressure sensor on the shield as well?

When you need a rank beginner to "noob-test" this board, let me know (or post up).
Thanks for the open-beta, though

Firmware loads up well through the .bat file.

Having a hard time compiling the APM demo.

In function 'void Init_PPM_PWM4()':
error: 'TCCR4A' was not declared in this scope In function 'void TIMER4_CAPT_vect()':
In function 'void loop()':

Great looking board though!

Where's the datasheet that's being referred to in the example?

but wait, is that WATER in that pint glass?

@John_C: Use Arduino IDE to compile PPM_decoding.pde and Timers.pde (both in same folder) and make sure you have selected Tools>Board>Arduino Mega (for the ATmega1280).....note do not mix in any of the ap_apm_ files...they are for the atmega328. Make sure your programming cable is in the ATmega1280 programming port to upload the new "sketch"

@Doug - straight grey goose. it was a work day. =)

Thanks for the guidance Michael, I'll give it a whirl.

Got mine up and running ! Good quality board, Testing Remzibi OSD too,

Any info on how the stackable shields will pinout?

I currently have my FTDI pins pointing up, and can see how Mark's may have an advantage.

Ok i was able to make more boards, i have 5 in stock. If you want one, either if is out stock, you can buy, but it will be shipped in around 1 week.

The board is working fine so far! The RC will virtually the same.

Many thanks for the feedback's!
