ADM42 / UIM42 Stepper Motor Driver
Product Link
[edit]Description
[edit]The ADM42/UIM42 is a miniature pulse and direction stepper motor driver designed for NEMA17 integrated stepper motors. With a compact size of 42.3 x 42.3 x 21mm, it can be directly mounted to NEMA17 (42mm) or NEMA16 (39mm) stepper motors.
Featuring a built-in 32-bit digital chip with advanced control algorithms for vibration suppression and low heat generation, the ADM42 delivers smooth, quiet operation. It supports standard RS232 serial commands and offers protection functions including overvoltage, undervoltage, and overcurrent.
With a DC input voltage range of 12-32VDC (recommended 24VDC) and continuous output current of up to 1.58A (2.2A peak), this driver is well-suited for small automation applications.
