Description

Stepper motor driver based on TB67S249FTG. It allows you to control a stepper motor with voltage from 10 to 47V, with a maximum current of 1.8A. The controller can be controlled using: USB, Serial TTL, I2C, RC (PWM modeling), analog input or quadrature encoder. Controller configuration is done via USB and dedicated software.

The controller is equipped with an Active Gain Control (AGC) system that automatically reduces the stepper motor current below the set limit based on the actual motor load and Advanced Dynamic Mixed Decay (ADMD), which dynamically switches between slow and fast decay modes based on real motor current, providing higher performance and smoother steps at high speed.
