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.
Size: 15mmX20mm (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
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
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
6, thermal shutdown circuit, undervoltage lockout, crossover current protection;
7, the ground short-circuit protection
and load short-circuit protection
