This driver is brand Leadshine (The most famous stepper driver company in China), and STEPPERONLINE is the biggest distributor of Leadshine in China.

This is a versatility fully digital stepper drive implemented with Leadshine’s advanced stepper control technology. It is easy to use and it can be used to drive 2-phase and 4-phase motors(from Nema 14-Nema 23 size) smoothly with less heat and noise. It works with 20-36VDC voltage and can provide max 2.2A peak current. You can set the DIP switches or tune the software to get the microsteps and current you need.
