The TIC T500 Stepper Motor Controller +CON manufactured by Pololu is a versatile, high-performance motor control integrated circuit that can control a wide variety of two-phase stepper motors with an input voltage range of 3 to 5.5 V and includes connectors for easy connection to external components. It features an I2C, PWM, RC, TTL, USB, and analog interface for precise control. It is equipped with a powerful MP6500 motor driver that provides enough power to drive most NEMA-11, NEMA-17, and other NEMA-style stepper motors. The controller is also equipped with a number of protection features, such as stall detection and automatic current limiting, for safe operation. The TIC T500 is ideal for robotics applications, small CNC systems, and other projects requiring precise motor control.
