The TB6612FNG Dual DC Motor Driver Board is an advanced, high-efficiency motor control module designed for small mobile robotics, precision motorized actuators, and micro-controller-driven automation.
The TB6612FNG Dual DC Motor Driver Board is an advanced, high-efficiency motor control module designed for small mobile robotics, precision motorized actuators, and micro-controller-driven automation. Built around Toshiba’s TB6612FNG dual H-bridge IC, it utilizes low ON-resistance power MOSFET switches (R_DS(ON) ≈ 0.5Ω) to drive electric motors with minimal power dissipation, eliminating the need for bulky heat sinks.
The module can independently drive up to two bidirectional brushed DC motors or one 4-wire bipolar stepper motor. Operating with an output motor supply voltage (V_CC) of 2.5V to 13.5V and a logic voltage (V_CC) of 2.7V to 5.5V, it provides seamless compatibility with 3.3V and 5V logic levels (Arduino, ESP32, Raspberry Pi Pico, and STM32).
It features dedicated direction control pins (IN1/IN2) and speed control pins (PWM) per channel, as well as a standby pin (STBY) that puts the driver into a low-power sleep mode. The module incorporates built-in thermal shutdown protection, low-voltage detecting circuits, and internal flyback clamping diodes to protect connected microcontrollers from inductive back-EMF spikes.
