README
README.mdStepper-Motor-Controller
Designed a circuit board in KiCad to control the forward and reverse motion of a 6-wire stepper motor driver. The board uses an Arduino to control the direction. The board also requires a clock to modulate the motor speed.
The circuit schematic is presented below. It uses a quad D flip-flop followed by a quad two input multiplexer to control the positive and negative terminals of the two coils of the stepper motor.
The PCB was redesigned a year after to use SMD components and save space. It is a two layer board; the top and the bottom layer can be found below:

The first version of the board's PCB can be found below. It used all through hole components, and was used as a learning experience for KiCad and placement, and did not take into account the board's size.

Questions
How big is the Stepper motor driver PCB?
It measures 97 × 37.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stepper motor driver use?
24 parts, built around the 74LS157PC, 74LS175PC and TIP120. 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 Stepper motor driver KiCad files?
From the alexandercote/Stepper_Motor_Controller repository on GitHub, at the commit this page was made from: the board is V1 - 2016 - Through-Hole/Stepper motor driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stepper motor driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask alexandercote before reusing the design.
