Ah, they're using the MediaTek GPS and the old barometer...those aren't great really.  But you can't beat the price!

This makes me think, why doesn't 3DR also sell their stuff via Hobbyking. That would make APM availible to the masses.

The main critical things of multi rotor stabilization system are the sensors only. Following three differences are quite a big difference between APM2.0_2.5 & This one.

• No secondary processor for RC interface/failsafe
• Older sensors (more like the ones used in the original APM 1.0)
• No datalogging

This one  has all the advanced same sensors as that of APM2.5, with GPS it is costing some 100US$

Just a few years ago the GPS alone would have been more money than that.

We just need JLN to port ArduPlane/Arducopter to this!! 

Comment by Rana on September 9, 2012 at 2:07am

Because all the sensors and the microcontroller is the same, very less efforts required by a regular developer.

JLN already ported Arduplane2.6 and Arducopter2.7

Even a normal person with little bit hand-son experience on Arduino IDE can do it, Guide to port the firmware can be found here.

Thanks Rana, saw those links already, inspected the code before. I just need a board to do whatever minor modifications to the code are necessary.

Problem is that the board is out of stock on HK, but if someone were to lend/rent/give me a board, I'd be happy to port the software!

Some similar boards with ATMega 2560 (capable of ArduPlane and Arducopter being ported over):

http://www.cuav.net/store/product.php?id_product=11 (yet to compare)

http://www.diymulticopter.org/ (similar board shape and connectors to APM 1)

http://www.goodluckbuy.com/scrc-crius-all-in-one-pro-v1-0-multi-cop...(H/W best as compared to APM 2)

http://www.rcgroups.com/forums/showthread.php?t=1455433 (everything on one board; GPS too!)

http://flyduino.net/Flyduino-MEGA-Flight-Controller-CPU-Board 

Perhaps we could do a post on a H/W comparison. I'd do it, but exams.... No time. 

@ Rana, need to talk, sent you a friend request.

Kabir, I already accepted your friend request, couple of days back. You may send your message.
