The Q-Brain incorporates 4x 20A speed controllers in 1 device. All motor leads are pre-installed and are terminated with 3.5mm bullet connectors. Leads are 25 cm long which means that you can use this controller with frames up to 60 cm. It operates on 2-4 cells lipo and 5-12 cells Ni-XX (anyone still using these). Refresh rate is over 400Hz.
Weight of the speed controller is 112 grams and dimensions are ~70x62x11 mm. The Q-Brain is probably very similar to the Hobbywing Quattro ESC.
Advantage: Easy install
Disadvantage: If one of the esc's dies you can't use it with a quadcopter anymore (get a tricopter!)

Note: If you are using the Q-Brain with a KK2 board, then S3 (the white cable) has to be connected to M1 on the KK2 to power it.

Can someone explain the connections with APM, Q BRAIN, motor and receiver.
I am planning to install this Q Brain and APM2.6 on a a frame body for this frame below.
Now my question is the order for the "sandwich" I am preparing, so, first APM2.6(internal compass), then Q Brain, then on top GPS, or Q Brain, APM, GPS.
Any suggestion? Some metal plates between them to protect with compass and magnetic/electric interferences?
I do not want yet the external compass, my actual quad fly good so far.

will do....cheers
silabs not atmel chips,not simonk but blheli.... google it.
So did anyone flash this with Simonk?
But, I agree, in having a port like i2c, to get non time critical information back and to configure the speed control behavior would be awesome... I never remember how many beeps mean what :-(
OK, I have been wondering when somebody was going to make an all in one speed controller board. Now all they have to do is to put an full digital I2C connection on it and get rid of the PWM signal for speed control and gain current, voltage, and temperature status fed back from the board. (SIGH) Maybe Someday. . . .
Hi Robert, yes I noticed that after I put in the response, I also noticed that HobbyKing says that you can use their programmer with their version whereas no such option is listed for HobbyWing ones.
Hard to find anybody not in China or Hong Kong that carries any of them unfortunately (even EBay is from China).
I wish HobbyKing carried more of their multicopter stuff in their US warehouse.
