Frequently Asked Questions
Q: Is this 4-channel I2C motor driver module compatible with Arduino and Raspberry Pi?
A: Yes! This module uses standard I2C (IIC) communication with 5V logic, making it directly compatible with Arduino boards, Raspberry Pi, ESP32, STM32, and most other popular microcontrollers that support I2C.
Q: What type of motors can I use with this DC motor driver module?
A: This board is designed for brushed DC motors operating at 3–12V (recommended under 11V) with a peak current of up to 1.5A per channel. It is ideal for small to medium DC motors used in robotics, smart cars, and motorized platforms.
Q: How many motors can I control at once with this module?
A: You can independently control up to 4 DC motors simultaneously — each with its own speed and direction — using just the two-wire I2C interface from your microcontroller.
Q: Does the module require any additional components to operate?
A: You will need a compatible microcontroller (e.g., Arduino or Raspberry Pi), DC motors, and an appropriate power supply (3–12V for the motor drive side, 5V for logic). No battery or wireless module is included with this board.
