TeknoCrafters ULN2003 Driver Board & 28BYJ-48 Stepper Motor Kit (Blue)
TeknoCrafters ULN2003 Driver Board & 28BYJ-48 Stepper Motor Kit (Blue) The TeknoCrafters ULN2003 Driver Board & 28BYJ-48 Stepper Motor Kit offers a comprehensive solution for projects requiring precise motor control. This kit is ideal for both beginners and professionals looking to integrate stepper motors into their applications. Kit Components: 28BYJ-48 Stepper Motor: Rated Voltage: 5V DC Gear Ratio: 64:1 Steps per Revolution: 2048 steps (~0.1758° per step) Coil Type: Unipolar ULN2003 Motor Controller Board: Input Voltage: 5V or 12V (compatible with 5V for this motor) Control Inputs: Four digital inputs (IN1 – IN4) Indicators: Four LEDs displaying coil activation status Key Features: Precise Control: The 28BYJ-48 stepper motor rotates its shaft in discrete steps, allowing for accurate positioning without the need for external sensors. Easy Integration: The ULN2003 driver board facilitates straightforward interfacing between the stepper motor and microcontrollers, such as the Arduino UNO. Visual Feedback: Onboard LEDs provide real-time indication of the motor's operational status, aiding in debugging and development. Example Application Scenario: In robotics projects within the Phoenix, AZ area, this kit can be utilized to control the movement of a robotic arm. The precise step control of the 28BYJ-48 motor ensures accurate positioning of the arm, essential for tasks such as pick-and-place operations. The ULN2003 driver board simplifies the connection to a microcontroller, enabling efficient control and integration.
