- Wide power and control voltage ranges: input power 3–14 V and signal supply 2.2–6 V. Logic levels at 3.3 V and 5 V are supported, allowing easy compatibility with common microcontrollers. - On-board 3.3 V supply: provides 3.3 V at up to 100 mA to power your control system, reducing the need for an external regulator. - Polarity indicator on the back: printed marking on the backside of the board helps you wire connections correctly and quickly. - Dual H-bridge motor driver: can drive two DC motors simultaneously or a single 4-wire two-phase stepper motor, enabling versatile motor control in a compact package. - Practical compatibility: suitable for microcontroller platforms such as Arduino, Raspberry Pi, and other 3.3 V/5 V logic systems, simplifying integration in projects and prototypes. - Performance and simplicity: a single board solution for motor control with flexible power and logic options, designed to support compact robotics, automated systems, and educational demonstrations. - Typical use scenarios: - Small robotics projects that require independent control of two DC motors for left and right drive. - Stepper motor or positional control applications using a 4-wire two-phase stepper motor for precise movement. - Prototyping and education with common microcontrollers (Arduino, Raspberry Pi, ESP32) where a simple dual motor driver is needed. - Applications and benefits at a glance: - Robotics: drive dual-wheeled robots or motorized chassis with straightforward wiring and compatible logic levels. - Automation and positioning: combine two motors or one stepper for compact, affordable motion control. - Education and hobby projects: learn motor control concepts with a single board that supports both DC motors and steppers, while matching 3.3 V and 5 V control signals.
