Bipolar Stepper Motor Driver – PoStep25-256

Description

PoStep25-256 is high performance and low-cost bipolar stepper motor driver with a Smooth tune – stepping motor control.

The PoStep25-256 is a high-performance, cost-effective stepping motor driver with Smooth tune – intelligent stepping motor control. The driver incorporates an advanced architecture and surface mount technology to achieve an exceptional power density. Moreover copper on the printed circuit board is 2 times thicker than in most Printed Circuit Boards. In conclusion, PoStep25-256 has state of the art thermal design. Thick copper and additional heatsink guarantee the best thermal performance and low heating. Low footprint, high power density, and robust design is a key for reliable bipolar stepper motor driving.

It can drive bipolar stepper motors at a maximum 2,5A. Beside Nema17, also some Nema23 stepper motors can be driven.
