Specification:
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: 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
performance
Application:
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 A rduino code, direct drive motor
Features:
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
