ADM42 Stepper Motor Driver

Product Overview​

The ADM42 is a compact, cost-effective digital stepper motor driver designed for NEMA17 and NEMA23 frame motors. Operating on 12-48V DC with output current from 1.0A to 4.5A, the ADM42 provides reliable pulse/direction control for a wide range of motion control applications at an affordable price point of $35.00.

The ADM42 features advanced microstepping technology with resolution up to 256x (51,200 steps/rev), ensuring smooth motor operation and resonance-free performance across the entire speed range. Opto-isolated pulse/direction/enable inputs provide clean signal reception and excellent noise immunity in industrial environments. The automatic current reduction feature reduces motor heating during idle periods.
