1,DRIVER AND WIRING: Composed of driver and wiring, and integrates the functions of 2 general 2 phase stepper drivers in a driver housing, saving space and wiring. 2,CONTROL 2 MOTORS: Can input 2 different pulses, direction and enable control signals at the same time to control 2 different motors without interference with each other. 3,STANDARD WIRING: The motor wiring uses 2.54MM standard sockets, the flat cable uses a single PH head 24AWG wire, the length is 300MM, and the signal wiring uses 26AWG wire. 4,APPLICABLE MOTOR: The subdivision number of each motor is a multiple of 2, which can be adapted to 57, 42, 39, 28, 24, etc. 2 phase stepper motors below 2A. 5,WIDE APPLICATIONS: Widely used in automation equipment, such as 3D printers, engraving machines, laser machines, packaging equipment, automated production lines, etc. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
