ROS 2 robot builds
A maker-published or maker-linked ROS 2 driver means it drops into a ROS 2 / Nav2 stack without a custom node.
Engineering inferenceNo-load speed, rated performance and stall limits describe different operating points. A stall specification is not a continuous operating rating.

Max range is the printed figure at the stated target reflectivity; accuracy is the typical datasheet value. Scan frequency is the default rotation or frame rate.
Specifications
Motor performance
No-load, rated-load and stall figures retain their separate test conditions.
Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
