TB6612FNG controller, double H-bridge controller driver.
Allows to control up to 2 current motors continuous or bipolar stepper motor. It also allows to control a unipolar stepper motor configured as bipolar.
Ideal for projects with ARDUINO. You can use it with PIC, AVR, STM32.
An improved version of the L298N.
H-bridges are made up of MOSFET transistors, rather than BJT transistors as in the L298N.
The TB6612FNG has better efficiency and smaller dimensions than the L298N.
Controller TB6612FNG DC PAP motor features:

- Minimum operating voltage: 4.5 V
- Maximum operating voltage: 13.5 V (15V max)
- Maximum current: ± 3A per channel (1.2 A direct current per channel)
- Logic voltage: 5V

- Measurements:
* Inner diameter D: 5mm
* Outside diameter D: 14mm
* Width - dimension B: 5mm
* Dimension C1: 1mm
* Dimension D1: 16mm
- Quantity: 1 unit
