I'm stumped. All they say is "For the multi-rotor fans. Coming soon." Anybody got a guess what it is?
@Ellison Someone has :) http://www.multircshop.com/site/index.php?route=information/informa...
I cant wait, Hobbyking I'm sure will keep this a reasonable price range which makes it even better.
Thanks Dave. That KK plus platform, sounds interesting. Too bad it take some much hacking to get working.
Also it answers the question Simon has about that that 5th input was:
@John, really? I thought the 2560 had more power than a 328, 168, etc? What does it have more of then? Just more IO and more RAM?
It would be really awesome if it came in purple.
@Lefebvre: Yes, that pretty much sums it up. The only thing that might make a difference is that the 1280/2560 has more hardware PWM channels, making it easier to drive servos/motors.
Which we then do through a 328 anyway... ;)
R_Lefebvre, No you got it backwards. The 328 on APM sums the PPM inputs into a format the Mega 2560 take tak ein in on one channel instead of reading 8channels with 8 pins thus limiting free resources on the 2560. Then, we smartly use the hardware timers within the 2560 which make PWM functions out for 8 or more channels of outputs to drive servos or speed controls. To say the 328 and 2560 have the same "power" is some serious over simplification. Bascially, they allow us to use the same IDE and more or less the same code base, but when we get into hardware performance, it's apples and oranges. See the chart below about PWM outs. 6 PWM outs on a 328P isn't going to cut it for an Octo.
Arduino board models
But the processor core and hence math performance is exactly the same for a 328/2560, so we run into the same computational limitations when trying to make sense of the sensor data and calculate an AHRS solution. The performance gain from extra PWM hardware is marginal in this regard.
