TB6612FNG / DRV8833 Dual Motor Driver Module | 1.2A / 3.2A Peak | CW/CCW/Brake/Stop | Arduino Microcontroller

TB6612FNG / DRV8833 Dual Motor Driver Module — 1.2A / 3.2A Peak | CW/CCW/Brake/Stop | Arduino

A compact dual H-bridge motor driver module based on the Toshiba TB6612FNG or Texas Instruments DRV8833 IC — providing independent bidirectional control of two DC motors (or one stepper motor) from any microcontroller with PWM output. The H-bridge architecture enables full CW/CCW rotation, PWM speed control, active braking, and coast (stop) modes for each motor channel independently. Built-in thermal shutdown and low voltage detection protect the driver IC from damage under fault conditions. The 0.8×0.8 inch form factor fits in compact robot and automation projects. Available in TB6612FNG (welded), TB6612FNG (solderless), and DRV8833 variants.

Key Features

• ✅ Dual H-bridge — independent bidirectional control of 2 DC motors or 1 stepper motor
• ✅ 1.2A average / 3.2A peak per channel — handles small to medium DC motors
• ✅ CW/CCW/brake/stop modes — full motor control including active braking
• ✅ PWM speed control — smooth speed control via PWM signal from Arduino
• ✅ 2.7V–5.5V logic supply — compatible with Arduino (5V) and ESP32/STM32 (3.3V)
• ✅ Thermal shutdown — protects the driver IC from overtemperature damage
• ✅ Low voltage detection — protects motors from undervoltage operation
• ✅ Compact 0.8×0.8 inch — fits in small robot and automation project enclosures
• ✅ Standby control — STBY pin enables low-power standby mode

Arduino Wiring (TB6612FNG)

1. Connect VM to motor supply voltage (2.5V–15V).
2. Connect VCC to Arduino 5V (logic supply).
3. Connect GND to Arduino GND.
4. Connect STBY to Arduino 5V (or a digital pin) to enable the driver.
5. Connect AIN1, AIN2 to Arduino digital pins for motor A direction control.
6. Connect PWMA to Arduino PWM pin for motor A speed control.
7. Connect motor A wires to AO1 and AO2 terminals.
8. Repeat for motor B (BIN1, BIN2, PWMB, BO1, BO2).

Frequently Asked Questions

Q: Can I drive a stepper motor with this module?
A: Yes. Connect the two coils of a bipolar stepper motor to channels A and B. Use a stepper library (e.g., AccelStepper) to control the step sequence.

Q: What is the difference between “welded” and “solderless” TB6612FNG variants?
A: The “welded” variant has header pins pre-soldered. The “solderless” variant is supplied without header pins, allowing you to solder your own headers or wires directly to the PCB pads.
