Joystick Stepper Motor Controller

This is a pulse generator for a stepper motor driver using a joystick. It is a board that contains an Arduino-compatible microcontroller and circuitry for controlling up to 2-channel (2-axis) stepper motors. The board has multiple options to develop stepper motor-related control systems, from a 2-axis analog joystick to a trimmer potentiometer to a 7-channel open collector TTL output to interface stepper drivers with optocoupler inputs, etc.
