Stepper 29 Click is MIKROE’s latest addition to its lineup of motor control Click boards, designed to simplify and accelerate embedded development. Built for engineers working on motion control, automation, robotics, and precision positioning systems, this compact add-on board enables fast prototyping and reliable proof-of-concept development within the mikroBUS ecosystem.
At its core is Toshiba’s TB67S579FTG, a PWM chopper-type driver for 2-phase bipolar stepper motors. It supports a wide motor supply range from 4.5V to 34V and delivers up to 1.8A of output current, all from a single VM supply thanks to its integrated regulator.
The motor control Click boards offers fine control over motor performance, including adjustable current thresholds, multiple decay modes, and microstepping up to 1/32 resolution. An onboard I2C port expander further extends configurability, giving developers more granular control over driver behavior.
Performance is where the Stepper 29 Click stands out. It uses continuous sine-wave current control for smoother, quieter operation even at full-step modes while second-generation automatic gain control (AGC) ensures stable current regulation. Integrated stall detection adds another layer of reliability, helping prevent motor lockups during operation.
Like other Click boards, it fits seamlessly into MIKROE’s mikroBUS™-enabled ecosystem, now nearing 2,000 boards.
The inclusion of ClickID allows automatic recognition by the host system, reducing setup time and minimizing configuration errors. Combined with mikroSDK’s open-source libraries, developers get a flexible and ready-to-use platform for rapid evaluation and customization across a wide range of embedded applications.
Leadership Comment
Comments Nebojsa Matic, CEO of MIKROE: “This new Click board is ideal for stepper motor control in office equipment like printers, scanners and copiers, as well as a range of commercial and industrial equipment, including vending machines, 3D printers, conveyor systems, robotic arms and CNC machines. It is part of our 145+ strong family of motor control Click boards and over 873 projects – with working code – featuring the Stepper 29 Click can be found on MIKROE’s embedded projects platform, EmbeddedWiki.”
