The maximum current is 2.5A. DRV8825 driver with 4-layer PCB board, better heat dissipation performance. The chip internal resistance is smaller, lower heat, better heat dissipation.
Manufacturing process: SMT mounting machine manufacturing, non manual welding, higher yield rate, and more stable performance.
Six different stepping resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, 1/32-step.
Widely used: DRV8825 driver board is widely used in 3D printers and small CNC machines.
