DRV8833 Motor Driver Module

  This module is much more efficient than the traditional L298N, and its size is significantly reduced. Within the rated range, the chip hardly generates heat, making it more delicate. Therefore, we recommend it for users with some hands-on experience. Please be extra careful when wiring, paying close attention to the polarity.

  The DRV8833 motor driver module can directly replace the TB6612 driver module as the pins are mostly fully compatible.

Specifications

VM Motor Voltage: <12V

VCC Chip Voltage: 2.7~5.5V

Output Current: 1A

Control Method: PWM

Instructions for Use

The STBY pin is connected to the microcontroller's IO pin. When STBY is set to 0, the motors will stop completely, and they will only work when STBY is set to 1. Once STBY is set to 1, the motor's forward and reverse directions are controlled through AIN1, AIN2, BIN1, and BIN2.

The A side (AIN1 and AIN2) can only control the AO1 and AO2 pins, while the B side (BIN1 and BIN2) can only control the BO1 and BO2 pins. Therefore, it is a dual-channel motor driver. The speed is controlled by the PWM duty cycle, which adjusts the motor speed through the duty cycle.

Hardware Connection

Hardware Connection

The main pins of the DRV8833 driver module include: VM, GND, xIN1, xIN2, xOUT1, xOUT2, (where x can be A or B for different drive channels).

• VM connects to the motor power supply (make sure the voltage matches your motor's specifications).
• GND Connects to the Arduino's GND and the power supply's GND.
• AIN1 and AIN2 control the motor direction and speed of channel A. They are connected to the PWM output pins of the development board.
• BIN1 and BIN2 control the motor direction and speed of channel B, and are also connected to the PWM output pins of the development board.
• AOUT1, AOUT2 are connected to the two endpoints of motor A. BOUT1, BOUT2 are connected to the PWM output pins on the development board.
• BOUT1, BOUT2 are connected to the two endpoints of Motor B.

The following wiring is adapted to this example:

Usage Method

The following is a basic routine for controlling a TB6612FNG module to drive a DC motor using the development board. This example only shows controlling one motor; to control a second motor, simply repeat the setup and use BIN1, BIN2.
