A4988/DRV8825 stepper motor driver extend board/external panel 

Specification:

1. Can use A4988 and DRV8825, pay attention on the direction when install.
2. All jumper wires turn to ON DP, show 16 subdevision (A4988) or 32 subdevision (DRV8825).
3. Jm connect with stepper motor.
4. JV connect 5V and 12V-24V power supply.
5. E/S/D/G respectively connected with Enable/Step/Dir/Gnd driver singal output.
A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the "step" input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed).
