MIKROE-6903

MIKROE-6903 is a Stepper 29 Click compact add-on board for control of bipolar stepper motors in motion control, automation, robotics, and embedded positioning applications. It is based on the TB67S579FTG, a PWM chopper-type 2-phase bipolar stepper motor driver IC. This IC supports a motor supply operating range from 4.5V to 34V with up to 1.8A output current, enabling motor drive using a single VM supply thanks to the integrated internal regulator. It features manual current threshold adjustment, integrated protection mechanisms, configurable step resolutions up to 1/32 microstepping, flexible decay mode selection, and extended configuration through a I2C port expander for advanced driver control. Stepper 29 Click features Advanced Microstepping with continuous sine-wave phase current for ultra-smooth, low-noise operation, even at full-step mode. Includes AGC 2nd generation for automatic current regulation and integrated stall detection to prevent motor stalls.
