For those who might be interested, this thread is being followed-up here.
Any option to use a MEGA. I have some motor shields I would like to reuse.
As far as I know, there is no support for any 8-bit microcontroller for micro-ROS. Maybe you can try using a bare XRCE-DDS application.
You are right. So for now I will be working with ROS 1. Then eventually can upgrade to ROS2 with 32 bit microcontrollers.
