Electrical Design
This page contains information about the quadcopter capes designed for our Beaglebone quadcopter. Design files for these are available here.
The version 1.0 board served as a test platform to ensure that we could spin the motors and get data from the IMU (without having to physically solder on an MPU-6050). Additionally, it was used to verify the mechanical design, and get a general idea about the weight of the quadcopter when fully created.
The version 2.0 board changed the form factor slightly due to the addition of a camera and an ultrasonic sensor. Additionally it flips the direction of the MPU-6050 changing the direction of "forward."
Version 3.0 incorporated a barometer (BMP 180) and GPS. It also moved the TRIG and ECHO pins from PRU 0 to PRU 1.
Version 3.1 incorporated minor fixes to 3.0 wiring (moved the GPS so it wouldn't hit the USB dongle).
Version 3.2 added a battery gas gauge (MAX 17044) to check battery voltage and estimate flight time.
