Overview
Board motor stepper is an open-source printed circuit board by Socketto, from the Socketto/board_motor_stepper repository on GitHub. It is a 16-layer board of 100 × 64 mm with 25 parts on 31 nets, routed with 219 tracks and 3 vias.
Its parts include 5 resistors, 4 capacitors, 1 transistor and 1 inductor. It belongs with the robots and motor control boards of this library.
README
README.mdThis board, designed with KiCad 9.0 and programmed with MPLAB X, is capable of driving a bipolar stepper motor (such as those used in printers).
It is programmed to be controlled via a standard RS-485 interface with a custom protocol but is already prepared to be integrated into a larger network of boards with hardware addressing and a standard protocol (such as Modbus).
Currently, to control the motor, simply send the character '1' to move it clockwise or '2' to move it counterclockwise. As feedback, the board will send back the character '5' (ACK).

Questions
How big is the Board motor stepper PCB?
It measures 100 × 64 mm and has 16 copper layers, 1.6 mm thick.
What parts does the Board motor stepper use?
25 parts. 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 Board motor stepper KiCad files?
From the Socketto/board_motor_stepper repository on GitHub, at the commit this page was made from: the board is board/001/001.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Board motor stepper design in my own project?
Its repository states no licence, so its author keeps all rights: ask Socketto before reusing the design.
