All about the product
The stepper motor driver based on the DRV8825 system allows controlling a motor with a current consumption of up to 1.5 A (with cooling up to 2.2 A) per coil, when powered by up to 45 V voltage. It has six driver modes: full step, 1/2, 1/4, 1/8, 1/16, and 1/32 step.
Key features:
- The module has a simple interface to control steps and direction
- Can operate in six modes: full step, half step, 1/4 step, 1/8 step, 1/16 step, and 1/32 step
- Using a potentiometer, the maximum motor current can be controlled, allowing motors to use a voltage higher than the rated voltage
- Motors can be driven with a voltage from 8.2 V to 45 V
- Current consumption up to 2.2 A (1.5 A without external cooling)
- Due to the built-in voltage regulator, the user does not need to have additional logic for the power supply
- DRV8824 works with systems that have a logic voltage of 3.3 V and 5 V
- It is protected against overcurrent and temperature, and the short circuit also has a system that blocks startup when the voltage is too low
- To increase the heat dissipation surface, the board is made using four-layer technology with a thickened copper layer
- Open mass field from the bottom, allowing soldering of cooling elements
- In terms of dimensions and wires, the module is compatible with a system based on the A4988 driver
Specifications:
- Supply voltage: 8.2 V - 45 V
- Continuous current per coil: 1.5 A
- Maximum short-term current per coil: 2.2 A
- Logic power supply voltage: 2.5 V - 5.25 V
- Resolution: 1, 1/2, 1/4, 1/8, 1/16, and 1/32 step
