Features and advantages compared to 49881. Maximum current 2.5A2. Supports up to 32 subdivisions3. 4-layer PCB board, better heat dissipation performance4. Smaller chip internal resistance, lower heat generation, better heat dissipationParametersSize 15mm*2mm (same as 4988)Drive power: 2.5ASubdivisions: 1, 1/2, 1/4, 1/8, 1/16, 1/32Manufacturing process: SMT placement machine manufacturing, non-manual welding, higher yield rate, more stable performanceSuitable for: occasions where stepper motors need to be driven. It is a necessary module for building 3D printers, CNCs, engraving machines, etc. Supported 3D printers include Prusa Mende, ultimaker, printbot, makerbot, etc.Feature1. Suitable for driving stepper motors below 8.2-45V 2.5A;2. Only simple step and direction control interface;3. Six different stepping modes: full, half, 1/4, 1/8, 1/16, 1/32;4. Adjustable potentiometer can adjust the maximum current output to obtain a higher step rate;5. Automatic current decay mode detection/selection;6. Overheat shutdown circuit, undervoltage lockout, cross current protection
