Description of DRV8825 Stepper Motor Driver Module

The DRV8825 Stepper Motor Driver Module is a high-performance bipolar stepper motor driver based on the Texas Instruments DRV8825 IC. It is designed to provide precise control of stepper motors, featuring adjustable current limiting, microstepping down to 1/32 step, and built-in protection mechanisms that include overcurrent, overtemperature, and undervoltage lockout.

Compatible with both 3.3V and 5V logic systems, the DRV8825 module is a drop-in replacement for the A4988 driver in most configurations, offering enhanced current capacity and higher microstepping resolution


Key Features


  • Simple step and direction control interface
  • Microstepping support: Full, 1/2, 1/4, 1/8, 1/16, and 1/32 step
  • Adjustable current control via onboard potentiometer
  • Operates directly with both 3.3V and 5V logic
  • Intelligent chopping control for optimal current decay mode
  • Over-temperature, over-current, and short-circuit protection
  • Built-in low-dropout voltage regulator for logic supply
  • Exposed PCB pad for improved heat dissipation
  • Pinout and size compatible with A4988 driver modules
  • Manufactured using the SMT process for high reliability and performance

Frequently Asked Questions (FAQ)


What is the maximum current the DRV8825 can handle?
The module can deliver up to 2.2A per coil with proper cooling (heatsink and airflow). Without extra cooling, it’s recommended to keep the current below 1.5A to avoid overheating.

Is the DRV8825 compatible with A4988 driver modules?
Yes. It is pin-compatible with A4988 and can serve as a drop-in replacement in most cases. The DRV8825 also offers higher current handling and supports finer microstepping (up to 1/32-step).

What microstepping resolutions does it support?
The DRV8825 supports six microstepping modes: full step, 1/2, 1/4, 1/8, 1/16, and 1/32. This enables smoother and more precise control of stepper motors, particularly in 3D printing and CNC applications.

How do I set the current limit?
The current is adjusted using the onboard potentiometer. You can measure the reference voltage (Vref) with a multimeter and use the formula:
Current Limit (A) ≈ Vref × 2
(This assumes a 0.1Ω sense resistor, which is standard on most boards.)

What protections are built into the module?
The DRV8825 includes built-in protection features such as overcurrent protection, overtemperature shutdown, undervoltage lockout (UVLO), and short-to-ground or load short-circuit protection.
