Hi @felmue, Yes, I mean that module. I will look into the documentation you provided, thank you. Regarding the number of servos I mandated the student - i teach art students - to scale down from his initial proposal of 24 servos, because of the logistics implied. He came to the class, proposing 13 servos with this module arguing that it should work, so here we are, trying to make it work. Thank you for your time.
