Stepper motor drive + control serial port 2A current
Stepper Motor Drive Module User Manual
HP230-TTL232
I. Overview:
HP230Is a small stepping motor driver module, as long as it is a two-phase four-wire stepping motor.
This module communicates with the host computer through TTL232. The module has automatic acceleration and automatic deceleration programs to ensure that the stepping motor does not lose steps during the driving process.
Product application:
● Controlling stepper motors;
● Program-controlled trolley;
