Quadcopter control board - part 1
Quadcopters and custom Eagle parts So I finally started my quadcopter project! I want it to do certain things - for simplicity, I wanted to use cheap modules that you can find on Ebay or Amazon for the accelerometer, gyroscope and magnetometer. I decided to add a micro USB port as a convenient 5 V power source, but quickly reasoned that full USB support with a FT232RL chip would be an easy way interact with the board and to spit out debug information. So I picked up a bunch of micro USB with through-hole female ports from Ebay for next to nothing... then promptly realised they were completely non-standard and I would have to create my own custom Eagle part . This turned out to be really quite simple. With digital vernier calipers in hand the footprint part I created (inset) in a prototype design turned out to be near perfect - result! For the accelerometer and gyroscope I'm using a MPU-6050, and for the magnetometer, a HMC5883L module. Essentially the design is clo
