The DM860I is a digital microstep driver for NEMA 34-size stepper motors, rated 2.4–7.2 A per phase at 20–80 VDC. It uses digital current control with DIP-switch microstep and current settings, and its 80 VDC ceiling lets it run higher bus voltages than common 24–48 V analog drivers, which helps hold torque at speed. It suits CNC routers, mills, plasma tables and other builds that need smooth, quiet motion from a large stepper. It is a bare driver board: no motor, power supply or controller is included, and it is not a plug-and-play unit for beginners.
