This is an amazing price for a very capable multicopter flight controller board with GPS: just $65!
The MultiWii team has been using the ArduCopter code to add navigation elements to what used to be just an RC controller (the board is based on the same Atmega2560 processor as APM). This looks like a great opportunity to see how well it works. Ordered!
It looks like the main differences between this board and APM 2.5 (aside from size, connectors and enclosure) are:
- No secondary processor for RC interface/failsafe
- Older sensors (more like the ones used in the original APM 1.0)
- No datalogging
Still, an amazing price and great way to get started with the MultiWii software.
From the product listing:
The MultiWii PRO is a gyro/accelerometer based flight controller that is loaded with features. This version of the MultiWii supports direct connection of a GPS module (package includes MTK 3329 GPS module) allowing for ultra-precise positioning functionality. With expandability options and full programmability, this device can control just about any type of aircraft. This is the ideal flight controller for your multi-rotor aircraft.
Features:
(MultiWii PRO)
• SMD component design with Atmega2560
• ITG3205 Triple Axis Gyro
• BMA180 Accelerometer
• BMP085 Barometer
• HMC5883L Magnetometer
• Servo output for camera pitch and roll control
• Supports direct connection of GPS module (MTK 3329 GPS module included)
• On-board USB connection for programming
(MTK 3329 GPS Module)
• Based on MediaTek Single Chip Architecture.
• L1 Frequency, C/A code, 66 channels
• High Sensitivity, Up to -165dBm tracking, providing superior urban performance
• DGPS(WAAS, EGNOS, MSAS) support (optional by firmware)
• USB/UART Interface
• Supports AGPS function (Offline mode: EPO valid up to 14 days)

hey i tried to use the ardupilot but it doesn't compile, some help please!
newbie. if it is a clone of http://www.smartdrones.de/collections/flight-controls/products/mult..., which soft with gps can be upload?
thanx
Kabir, I already accepted your friend request, couple of days back. You may send your message.
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!)

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.
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!

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
http://ardupilotdev.googlecode.com/files/ArduPlaneNG2xR5.zip
http://ardupilotdev.googlecode.com/files/ArduCopterNG_2.7.zip
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.
We just need JLN to port ArduPlane/Arducopter to this!!
Just a few years ago the GPS alone would have been more money than that.
This one has all the advanced same sensors as that of APM2.5, with GPS it is costing some 100US$
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.
