Stepper 29 Click from MIKROE
BELGRADE, SERBIA — Stepper 29 Click is a new motor control Click board™ from MIKROE. The compact Click add-on boards enable developers to rapidly pro- vide proof-of-concept, then proto- type and code new embedded projects.
Stepper 29 Click is based on
the TB67S579FTG, a PWM chop- per-type two-phase bipolar step- per motor driver IC from Toshiba Semiconductor, which 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 mecha- nisms, configurable step resolu- tions up to 1/32 microstepping, flexible decay mode selection and extended configuration through a I2C port expander for advanced driver control. The Click board features advanced microstepping with continuous sine-wave phase current for ultra-smooth, low- noise operation, even at full-step mode. It also includes AGC 2nd generation for automatic current regulation and integrated stall detection to prevent motor stalls. Stepper 29 Click is a recent
addition to MIKROE’s 1970- strong mikroBUS™-enabled Click board family. The board also features the ClickID func- tion which enables automatic identification by the host system, simplifying use. Devices can be used on any host system support- ing the mikroBUS standard, and come with the mikroSDK open- source libraries, offering excel- lent flexibility for evaluation and
customization. Contact: MIKROE,
