for The interface is fully compatible with extensions. for communication via 12C and addresses can be modified. It can motors with direct PWM drive output. Up to four DC brush motors or two four-wire stepper motors can be connected.<br> Using TB6612FNG motor driver chip, 1.2A drive capability, 3.2A , L298N module.<br> TB6612MOSFET driver: 1.2A and 3A current per channel. it also has a lower motor voltage drop, so more torque can be obtained from the battery. Instead of using latches and FOR Arduinos PWM pins, we have a fully dedicated PWM driver on the chip. This chip handles all the motor and speed control on the 12C. Only two pins (SDA and SCL) are needed to drive multiple motors. Stackable design.<br> Supply Voltage: 8-35V<br> Logic Voltage: 5~12V<br> Reference Voltage: 5.5V<br> Output On-Resistance: 320-430m ohms per driver<br> Diode Forward Voltage: 1.2V per driver<br> Output Current of the Driver: ±2A<br> for Compatible: Yes<br> Product Dimensions: 6.8x5.2cm<br> Color: As Shown<br> Material: PCB<br> Package Contents:<br> 1 * TB6612 DC Stepper Motor Driver Module<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
