ROS 2 is supported on both 32 bit (arm32) and 64 bit (arm64) ARM processors. However, you can see here that arm64 receives Tier 1 support, while arm32 is Tier 3. Tier 1 support means distribution specific packages and binary archives are available, while Tier 3 requires the user to compile ROS 2 from source.
