Linking Multiple PCA9685 Servo Driver Boards
This follows on from the three part guide on how to connect servo motors to an Arduino using a PCA9685 servo driver and control them using JMRI. You can see the first video in the series here - https://youtu.be/ayOoUkdjHtg
To use more than 16 servos you'll need to link multiple PCA servo driver boards together. A few people asked me how to do this so I've put this guide together which shows how to set up the hardware and modify the sketches from the previous tutorials
