• TB6612FNG Datasheet (PDF)
• Schematic (PDF)
• Adopted ceramic capacitor, it has a more stable performance
• The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak)
• Built-in thermal shutdown circuit and low voltage detecting circuit
• CW/ CCW/ short brake/ stop motor control modes

• 2*5V servo motor (servo) port is coupled to its high-resolution high-precision timer - no jitter
• Up to four bi-directional DC motor and 4 PWM speed (about 0.5% resolution)
• Up to 2 stepper motor control, single / double-step control, staggered or micro-step and the rotation angle control
• 4-channel H-bridge: L293D each bridge chip provides .0.6 A (peak 1.2A) current and with thermal shutdown protection, 4.5V to 36V
• Large terminal terminals make wiring easier (10 - 22AWG) and power supply

• This product is a breakout board for Allegro's A4988 DMOS Microstepping Driver with Translator and Overcurrent Protection;
• This stepper motor driver lets you to operate bipolar stepper motors in full-, half-, quarter-, eighth-,
  and sixteenth-step modes, with an output drive capacity of up to 35 V and 2 A.
• The translator is the key to the easy implementation of the A4988.
• Simply inputting one pulse on the STEP input drives the motor one microstep.
• There are no phase sequence tables, high frequency control lines, or complex interfaces to program.
• The A4988 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened.
• Features
• Simple step and direction control interface
• Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
• Adjustable current control lets you set the maximum current output with a potentiometer,
  which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
• Intelligent chopping control that automatically selects the correct current decay mode
  (fast decay or slow decay)
• Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
• Short-to-ground and shorted-load protection
