Description: The module has an interface pinout is almost the same with A4988 stepper motor drive carrier, so that it can be used as a higher performance in a pull-down menu the plates replaced in many applications.
DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step).
It uses 8.2 - 45V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).

}Features:
- Simple step and direction control interface
- The interface can connect directly with 3.3V and 5V systems
- Support over-temperature thermal shutdown, over-current shutdown and under-voltage lockout
- Support short-to-ground and shorted-load protection
- Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
- 4-layer, 2 oz copper PCB for improved heat dissipation
- Adjustable current control support you to set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
- Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
- 45V maximum supply voltage
- Built-in regulator (needed external logic voltage supply)
Package included:
1 x Stepstick DRV8825 stepper driver
1 x Heat sink
สามารถใช้คู่กับฐานรองบอร์ดเพื่อประหยัดเวลาต่อสายไฟ

Exchange or return policy
Every item comes with a 30-day warranty. However, there are certain conditions that apply:
-
The customer should not be responsible for any self-inflicted damage, such as incorrect power connections (for example, supplying 5V instead of the required 3.3V for a sensor).
-
The product must be in perfect condition, without any breakage or damage caused by electricity (e.g., short circuits leading to electrical fires).
-
The store does not accept product exchanges due to customer misunderstandings, such as purchasing the wrong size for their project or buying something without eventually using it. Customers can inquire about the product details and ensure compatibility before making a purchase by contacting us through our Line account @modulemore during business hours. Please note that there may be delays in response between 12:00 PM and 2:00 PM.
Return Policy: To initiate a product return, customers must provide the original receipt or a copy for quick verification. Returns can be sent to our store address by following these guidelines:
- Provide a detailed description of the damaged item(s).
- Mention any tests or experiments conducted by the customer.
Please note that the store reserves the right to make the final decision regarding product replacement or refund.
