A variety style signal supply logic input selectable, which compatible with lots of MCU and other controller board, such as Mach3 USBCNC Raspberry Pi and so on.
Microstepping: 1/1, 1/2A, 1/2B, 1/4, 1/8, 1/16(default).
How it works
Input and Output
Normal connector and Quick connector is parallel. ONLY ONE CONNECTOR REQUIRED AT ONE TIME.
This picture shows how you can change the micro-stepping settings of the driver.
Output Limit current Adjust
You can approximate the current limit by the position of the marked point on the trimmer. DO NOT EXCEED YOUR MOTOR’S CURRENT RATING.
OR the current limit can be adjusted by measuring VREF and turning the trimmer. Connect the [+] of the voltmeter to VREF and the [-] lead to GND and read the value.
Current Limit = VREF ÷ 0.6801
So for example the Max current is: 2.81V ÷ 0.6801 = 4.1317A
