KAmod Motor Driver TB6612FNG - Dual DC Motor Driver
 
The KAmod Motor Driver TB6612FNG is a versatile, powerful, and easy-to-use motor driver module that allows for precise control of two DC motors (or one stepper motor) in terms of direction and speed, while also offering protection and a low-power mode. It is an ideal alternative to L298N-based modules. 
The TB6612FNG integrated circuit, developed by Toshiba, contains two independent H-bridges using MOSFET transistors. Each H-bridge can control one DC motor. The module allows for controlling DC motors with a voltage ranging from 4.5 to 13.5 V (VM). The integrated circuit's logic circuits (VCC) should be powered with a voltage between 2.7 and 5.5 V. The TB6612FNG can deliver a continuous current of up to 1.2 A per channel. The peak transient current can be up to 3.2 A. If you need more current for a single motor, you can connect both channels (outputs and control inputs), obtaining up to 2 A of continuous current.

====='''Motor Control'''=====
Each motor is controlled using two input signals ('''IN1''' and '''IN2'''), which allow for the selection of one of four functional modes:
*Clockwise rotation (CW)
*Counterclockwise rotation (CCW)
*Short brake
*Slow stop (Stop / High impedance)
 The two motor outputs (A and B) can be controlled separately, and the speed of each motor can be controlled using a PWM input signal with a frequency of up to 100 kHz. To bring the controller out of sleep mode, a high level must be applied to the ''STBY''' (STANDBY) input. A low level (default) puts the system into sleep mode (low power consumption).
