I want to create a drawing robot for my assignments. I think it will be helpful.This is my first project.This project is about building a simple drawing plotter robot that can automatically draw pictures and text on paper. It uses NEMA stepper motors to move a pen precisely along the X and Y directions.

Questions
How big is the Controller PCB?
It measures 86.6 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
27 parts, built around the ESP32-S3-WROOM-1-N8, TS-1088-AR02016 and TYPE-C-31-M-12. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Controller KiCad files?
From the alanrstalin2010/Drawing-robot repository on GitHub, at the commit this page was made from: the board is PCB/controller.kicad_pcb and its schematic PCB/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask alanrstalin2010 before reusing the design.
