==============================================

 A: irf1205 power NMOS independent 8 super low conduction loss, low calorific value, and there is no heat accumulation problem, no need to heat sinkIt is by no means an integrated single chip driver level

Instructions

Operating current regulation (Running Current)
Using the dial switchSW4, SW5,SW6 to adjust the operating current.

Holding current (semi-automatic)Function:

When the motor stops rotating (0.5 seconds no input step pulse), the operating current automatically halved.

Subdivision adjustment (Microstep)
Dial switch SW1, SW2, SW3 used to adjust the motor subdivision mode, a total of 8 kinds of subdivision mode:

LED indicator light
The green indicator light indicates that the work is normal:

Failed to connect the motor or the motor to open any phase;

Drive over current protection

Signal input port:

+5V: Yang end
CLK-: step pulse signal anode
DIR-: negative direction control signal
EN-: enable signal negative

Be carefulOffline enable signal is different from the other two signals, the user can not be connected, that is, no signal input, is to enable the driver to enter the operating mode; if there is a signal input, the driver will enter the sleep mode.

The driver board is based on standard common signal interface

Be carefulVCCValue5VWhen,RShort connection (no series resistance R);

VCCValue12VWhen,Rby1K~1.2KGreater than1/8WResistance;

VCCValue24VWhen,Rby2.7K~3.3KGreater than1/8WResistance;

RMust be connected to the controller signal.

Output and power port:
