I'm currently working on my first ROS project. Currently I'm running Melodic on a Jetson Nano with a Donkey Car base which is an Exceed Magnet RC car and a PCA9685 servo driver. I chose this hardware because I already had it. I have RPLidar with SLAM working and a realsense camera working. I still need to study up on a Navigation stack so I can tie everything together.

I'm having issues with with finding a way to control the Donkey Car base.

I found ros-i2cpwmboard however, I can't seem to get the package to compile. Am I on the right track with this package? Is it worth troubleshooting? Or is there a better option I should be looking at?
