Arduino CNC Shield V3 Engraving 3D Printer + 4x DRV8825 Stepper driver

Paket penjualan : 1pcs Arduino CNC Shield 4pcs driver DRV8825 4pcs allumunium heatsink Relative 4988 Features Benefits: 1, the maximum current of 2.5A. 2, up to 32 segments. 3,4-layer PCB, better heat dissipation. 4, the chip resistance is smaller, lower heat, better heat dissipation. parameter: Size: 1.5mmX2mm (same as 4988) Can drive current: 2.5A Subdivision: 1,1 / 2,1 / 4,1 / 8,1 / 16,1 / 32 Manufacturing Process: SMT placement machine manufacturing higher, non-manual welding, yield more stable performance Suitable for: Need to drive stepper motors. It is to build a 3d printer, cnc, engraving machine and other necessary modules. Supported 3d printer has Prusa Mendel, ultimaker, printbot, makerbot like. You can refer to the back of the Arduino code, direct drive motor DRV8825 features are the following: 1, suitable for driving below 8.2V ~ 45V 2.5A stepper motor; 2, only a 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 output current, resulting in higher step rate; 5, Automatic current decay mode detection / selection; 6, thermal shutdown circuit, undervoltage lockout, crossover current protection; 7, the ground short-circuit protection and load short-circuit protection
