turtle HAT for μBot

About μBot [educational floor robot]:  https://www.pcbway.com/project/shareproject/_Bot_[educational_floor_robot].html

With this HAT you can use the μBot as a floor robot without a smart device / PC. Forward and backward "steps", 90° turns, pause, clear… Like other floor robots. However, there are useful functions like undo and loop (details in the video).

The green one is my last order. I like black solder mask more, but the time matters... :) From my last order I made only some minor changes (spacing some traces and THT holes). You can see on the black ones.
