CRIUS ALL IN ONE PRO v1.0 Multiwii & Megapirate Flight Controller

Pros: You can use the mission planner with the ardupirateNG (i tried v2.7 r4), spending much less money than buying APM (v1 250usd, v2 200usd). Multiwii 2.1 also works fine. Full of documentation on the web, to get your drone work!

Cons: You have to put epoxy glue in both sides of the usb, because it is easy to break it when you put the micro usb cable .

Other: You can connect: Bluetooth module GPS modules (I will use ublox cn-06) Telemetry modules Sonar module (I have sr04 working)

Pros: It works! good soldering, small size, excellent selection of sensors (gyroscopes, accelerometers, magnetometers and baro) and ports, including a port USB. For this price, the perfect choice for building multicopter.

Cons: Weak connector USB - breaks off from the board, you must use the USB cable without latches. There are traces of flux on the board, but they are easily removed with alcohol. No instructions and software included

Other: best price for good device. and freeshipping

Pros: all most recent sensor is on this board! barometer is just too nice compare to the old BMP085. rely good design nothing to say on this , and for the price it's just perfect.. all connection are nice they minimize the number of wire to get everything working

Cons: pay attention to usb port, very fragile, 2 option there re-solder the outer grnd or hot glue the port

Other: mmmm buy buy buy buy im buying 4 more perfect working multiwii and megapirateng , addon bluetooth sonar wireless data gimbla all is test and everything work

Pros: cheap enough sensors tri up to octocopter possible MultiWii and MegaPirateNG flashable USB & FTDI Port enough ports for everything you need on a Copter

Cons: USB Port breaks off too easy (Can still be programmed via FTDI)

Other: Over all, I am totally satisfied with this board.

Pros: Has all sensors you would need. Plenty of information about this on internet. Runs and works with Megapirate NG (2.8+). Comes with bunch of wires to connect additional boards. Connectors are marked well.

Cons: Unless you know what you are doing it can be hard to setup.

Other: Takes care of all my quadcopter controller board needs and there are plenty of accessories here in DX for this (GPS, Bluetooth...).

Pros: Supports excellent firmwares (Multiwii/MegaPirate Awesome stability and control can be achieved. Price

Cons: Came with broken or missing bootloader which means that unless you have an AVR ISP programmer, some header pins, know where to solder those pins onto the board and how to re-burn the bootloader - this thing is a brick.

Other: Great board, it just might not be plug and play for your application.
