Stepper Motor Driver Module ULN2003

The ULN2003 APG is a convenient package of seven Darlington transistors, which means it's an easy way to drive up to seven loads up to 500mA to 50V maximum. This nice IC is mounted in a circuit board specifically designed to drive unipolar stepper motors, especially these 16:1 and 64:1 stepper gearmotors.

Stepper Motor Driver Features:

• Uses well-proven ULN2003 driver IC
• Maximum 500mA/channel (50V maximum)
• Socketed for direct connection to the 22305 16:1 and 22310 64:1 stepper gear motors
• Indictor LEDs show coil energization
• 4 presoldered input channel pins
• Works well with Arduino stepper and AccelStepper libraries
