This product is a carrier board or breakout board for the DRV8434S stepper motor driver from Texas Instruments (TI); we therefore recommend careful reading of the DRV8434S datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to approximately 1.2 A continuous per phase without a heat sink or forced air flow

• Output voltage: 9 V with 4% accuracy
• Input voltage: 1.3 V to 16 V (Note: minimum start-up voltage is 2.7 V)
• Typical efficiency of 85% to 95%, depending on input voltage, output voltage, and load
• Switching frequency: ~1.2 MHz under heavy loads
• Power-save mode that increases light load efficiency by reducing switching frequency
• Typical no-load quiescent currents under 1 mA
• 2 A switch current limit
• Typical continuous input currents up to around 1.6 A 
• Tolerates input voltage above output set voltage (output will track input)
• Integrated protections:
  • Over-temperature shutdown
  • Soft-start feature limits inrush current and gradually ramps output voltage
  • Under-voltage lockout
• Compact size: 0.515″ × 0.32″ × 0.1″ (13.1 × 8.1 × 3 mm)
• Weight: 0.4 g
