Description
TB6612 Four Channel H Bridge DC And Stepper Motor Driver Module is a 4 channel, stepper motor driver and controller board for Arduino, which is based on two TB6612 IC and another chip, known as PCA9685. The TB6612 chip is a driver IC for DC and stepper motor with output transistor in LD MOS structure with low ON-resistor. The first input signals, IN1 and second input signals, IN2, can select one of these four modes: CW, CCW, short break, and stop mode. The TB6612 produces 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes and can drive motors on 4.5VDC to 13.5VDC. This 4 channel driver can drive and control two bi-polar stepper motors or fore brushed DC motor, or one stepper and two DC motors.
Also the PCA9685 chip is a fully-dedicated PWM driver chip, and a good replacement of using a latch and the PWM pins which handles all the motor and speed controls over I2C. By using I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. It can be stacked with any other FeatherWing or with itself (each wing with a unique I2C address). By applying an appreciate feather stacking headers or feather female headers, user can connect it to a FeatherWing and make a flight gadget.
