Description
HATshield for Raspberry Pi 3 / 2 / B+ / Zero / Zero W enabling the control oftwo DC motorsusing theI2Cinterface. It is based ondual-channeldriverTB6612FNGandthe systemPCA9685which ensures12-bit resolution of control of the motor's rotations and their direction. It has a built-in voltage regulator5 V which can give a current with a maximum voltage of3 A. The module is supplied with the voltageof 3.3 V, and motorsfrom 6 V to 12 V. The kit also includes aset of screws and spacers.
Description of pins
For proper operation, it is sufficient to connectthe Raspberry Pito the slot for the GPIO pins. Pins are 6 screw connections ARK, allowing you to easily connect wireswithout soldering. They are responsible for the pins for the two motors and their power and ground.The module can also work as asimple motor driver thanks to additional pins to goldpin connectors. It also hasa built-in switch.
