Features:

1. Using high quality materials
2. Chip built-in error detection circuit (thermal shutdown (TSD), over-current shutdown (ISD), and power-on reset (POR))
3. High-efficiency motor current control (Advanced Dynamic Mixed Decay ADMD,
ADMD technology tracks the input current more closely than traditional mixed decay modes, thus realizing high-efficiency motor control at high rotational speeds)
4. Compact and lightweight size, beautiful component layout
5. Wide range of applications, suitable for a variety of industrial DIY occasions

Parameter:

Allow full step, half step, quarter step, 1/8, 1/16, 1/32 step operation
Maximum input voltage: 50V
Maximum output current: 4A (requires good heat dissipation)
The product adopts four layers of thick copper immersion gold PCB

Attention:

1. The product is sensitive to static electricity, please handle with care when using, and it is best to remove the packaging when using it
2. Please carefully confirm the installation direction before inserting the module into the motherboard,
it may be directly damaged when inserted improperly, and may even damage the motherboard
3. Please turn off the power when inserting/unplugging the module, and do not insert the driver module when the motherboard is powered on.
4. The module will be very hot during operation, avoid touching it during operation to avoid burns.
5. When installing the heatsink, please make sure that the heatsink is not in contact with the module pins or any other conductive location.
6. Please make sure to install the heatsink or air-cooling correctly when using! Please do not use it for a long time without heat sink!
