ArduPilot Mega Updates, updates!

I have several stuff i would like to explain! Let's enumerate them:

1.-The first batch of ArduPilot Mega's may be released this Wednesday 28.

2.- The lasted shield is ready (codename: Foxtrap) and has many advantages compared to the last board, including the Invensense gyros (cheaper and better against vibration), smaller board size, can be used on the top or in the bottom, build-in absolute pressure sensor (Bosch) and i removed the differential pressure sensor, but you can still add it as an optional expansion board.

The price still the same.... ;-)

Facts you already know about the shield:
-3.3V Regulator.
-Relay switch for cameras, lights or payloads.
-12-bit ADC.
-Build-in Data Logger (The Black Box).
-Piano DIP switch for servo reverse.
-Build-in FTDI, serial to USB.
-Dedicated Modem/OSD port.
-I2C Port for Magnetometer.
-Two buttons (one momentary, second slide).
-Expansion analogs ports and more.

You can give a look to the Eagle Files here:

Latest boards:

About the development names I use: Alpha1 never made it, Bravo1 is the one i sent to Julio (private release), Charlie1 luckily arrived late, Delta1 was canceled because i decided to remove the differential pressure sensor and add the absolute pressure sensor. Eco1 was also canceled because i switched the Gyros from ST to Invensense. Current released candidate is the Foxtrap1..

Check the new logo:

I will order the first batch this Monday, i hope they arrived fast to test and release!

I have many other stuff going on! I have to leave so you will see later.. ;-)

BTW, Thanks to Scott Plunkett for the Bosch absolute pressure sensor and Bill Premerlani for the Invensense gyros explanation!

  • Any news on when the board will be released?
  • Hi,
    What is the estimated price for the IMU shield?
    I have read ( that it was going to be about $139. Is there a more recent estimated price?

  • Randy,
    the new UAVDevBoard prototype has Invensense gyros too. It was tested from heli guys and it seems they solved their vibration problems, present with the old Lisy300AL. It was proved too that they are immune to 900MHz interference.
    Best regards,

    I'm wondering if the invensense gyros will really be vibration resistant. My 6dof frrom sparkfun uses invensense gyros ( and I've had a lot of issues with vibration. Now that could totally be my fault (it's a helicopter not a plane) but I've recently started testing with an analog devices gyro and it definitely seems better.

    I'd love to see some data from someone who has tested the vibration resistance of the various gyros and accelerometers...but until then..hopefully it'll all be ok!
  • that great, the xtend has great range, can't wait to try it on the mega
  • Developer
    No, still there for Ardupilot V1, is not fixable because the modem is sharing serial port... In mega will have dedicated port.
  • has anyone tested the Maxstream Xtend radio at all??
  • Did you guys find a fix for the XBee config resetting issue when leaving the XBee attached to AP when plugging in the battery?
  • Developer
    Well for me works after 15-20cm away....
