Stepper motor controler with USB / Serial / I2C / Pot / RC interfaces

The Tic T500 USB Multi-Interface Stepper Motor Controller designed to control a stepper motor easily (with quick configuration over USB using the Pololu's free software). The controller supports six control interfaces: USB, TTL serial, I2C, analog voltage (potentiometer), quadrature encoder, and hobby radio control (RC).

This version of the Tic uses an MPS MP6500 stepper driver and is ship with soldered header pins and terminal blocks.

This Tic controler operates from 4.5 V to 35 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (or 2.5 A max with sufficient additional cooling). As the Tic also support the current limiting features of steptick, you can also drive the stepper at higher voltage while keeping the current low to avoids the coil to burn (see this tutorial about the A4988 explaining this feature).

The Tic family of stepper motor controllers makes it easy to add basic control of a bipolar stepper motor to a variety of projects. It is a versatile, general-purpose modules supporting different control interfaces: USB for direct connection to a computer, TTL serial and I²C for use with a microcontroller, RC hobby servo pulses for use in an RC system, analog voltages for use with a potentiometer or analog joystick, and quadrature encoder for use with a rotary encoder dial.

Tic also have many settings that can be configured using the configuration utility (from Pololu for Windows, Linux, and macOS). This software make initial setup easy and allows in-system testing and monitoring via USB (a microB USB cable is required to connect the Tic to a computer).

Based on MP6500 stepper driver

The Tic T500 is based on the MP6500 IC from Monolithic Power Systems. This driver IC features automatic decay mode selection, using internal current sensing to automatically adjust the decay mode as necessary to provide the smoothest current waveform.
