Raspberry Pi + Aeroquad?

[fb39ca4]

I noticed that Raspberry Pis have GPIO pins, would those be enough to run a quadcopter?

Depends on your setup, the AQ code isn't written for Raspberry Pis but I'm sure it can be ported over. Are any of them PWM outputs, or capable of being PWM outputs? I don't know much about the Raspberry Pi.

You'll need at least 4 PWM outputs (one for each motor), some inputs for sensors, and some inputs for receiver channels (at least four, unless you use a PPM receiver in which case you only need three).

I don't see why it couldn't be done if you had the time and knowledge.

Ok. What types of inputs are needed for the sensors, and receiver channels? Digital or an ADC?

Depends on what sensors you use, there are analog and digital versions of pretty much every kind of sensor out there. The AQ shields are designed to use gyros/accels/magnetos with an I2C interface, the rangefinders are set up to be analog, barometer is I2C... I2C is digital, if you're unfamiliar with it.

But, that's not to say that you can't use different kinds of inputs, that's just what the AQ code is currently written for.
