The ULN2003 Stepper Motor Driver Module is a robust dual-purpose driver board based on the ULN2003A Darlington transistor array. It provides up to 500 mA per channel and supports motor voltages of 5–12 V, making it ideal for driving 4-phase stepper motors like the 28BYJ‑48. It includes onboard indicators, 5-line connectors, and easy logic-level control from Arduino, ESP32, or Raspberry Pi. Great for robotics, CNC, and motorized automation projects.
