For all the talk of the drone revolution, there remanes but 1 vehicle which is truly a plug & play drone for the masses: the AR Drone. In true dot com tradition, ifixit.com made zillions of dollars in venture capitol & never did a teardown of the 2.0, so it was time for the unemployed masses to step in.
The entire electronics assembly & battery are supported by a piece of foam. The boards still have many wires connecting to the frame, subjected to the full vibration.
A common 640x480 camera does the optical flow & seems to send some kind of compressed data. It may be a 30fps USB cam.
A custom AR Drone sonar circuit.
It's a mane brain board & sensor board, connected by
just 8 pins. The 2 cameras connect to the mane board. The front cam may output uncompressed data.
A common PIC serializes the data from all the sensors. Maybe it also fuses the sensor data.
The air pressure sensor is under a piece of foam designed to not touch it.
Standard gyro + accelerometer chip & unknown magnetometer, not that it matters since everyone is going to use the mpu9250 tomorrow.
with a trace antenna.
Under the can, it's a power management & USB chip from TI, some kind of flash & RAM from Micron. In usual modern fashion, the mane processor would be sandwiched under the big chip, so there would be no way to see it.
