Hello everyone. Even though programming is a familiar topic for me, I'm new to arduino programming and electronics as well. Due to that, I'm trying to minimize as much as possible the amount of wires I need to connect.
So, I'm trying to build an RC airplane, but I want to use an arduino for the flight controller. For my purposes, I need GPS, accelerometer, gyroscope and altimeter. I'm wondering if I can find (at a reasonable price) all of those sensors in a single chip or in two separate chips. In that way I'd minimize the amount of wiring needed to get the thing up and running and also de amount of pins (I guess) used in the arduino.
Please note, all tips you can give me for bluiding arduino-based rc-airplanes will be ver very well appreciated. Thanks a lot for your support

Pololu sells "10DOF" sensors that contain an accelerometer, gyro, magnetometer and an altimeter (pressure sensor).
