SMART STEPPER CONTROLLER

TDRmicro Smart Stepper Controller

Designed and assembled by TDRmicro in Oregon, USA, the Smart Stepper Controller is a versatile reference system designed to accelerate your innovation in industrial, agricultural, and home automation.

Built around the efficient PICĀ® RISC microcontroller architecture, with an integrated motor driver, user control options, and a power backup system, this solution ensures continuous performance even in unpredictable environments. The built-in real-time clock, along with an easy-to-use LCD interface, enables precise, time-sensitive operations for your projects requiring motor control.


  • Supports flexible microcontroller options in PIC16F and PIC18F families.

  • Features a robust motor driver for precise control of NEMA17 stepper motors.

  • Integrates a user-friendly display for configuration and monitoring.

  • Features reverse polarity protection and an automatic power backup switching circuit to auxiliary 12V DC battery source for uninterrupted operation.

  • Ensures accurate timekeeping with a temperature-compensated real-time clock, backed up by a coin cell battery.

  • The Smart Stepper Controller Board comes in a 100mm x 100mm form factor, takes 12V DC power via a standard barrel jack, and is designed to handle loads of up to 3A, making it suitable for demanding applications.

To support further development, we provide an SDK written in C, compatible with the PIC16F and PIC18F microcontroller families. The SDK enables comprehensive control of the system, empowering developers to customize and extend its functionality to meet specific project requirements.
