A3967 30V 750mA Stepper Motor Driver - Arduino Compatible
A3967 30V 750mA Stepper Motor…
(0)
A3967 Stepper Motor Driver This A3967 Stepper Motor Driver For Arduino is the most recent version of EasyDriver v44, which was created in collaboration with Brian Schmalz. When compared to previous versions, it offers more flexibility and control over your stepper motor . It is a simple stepper motor driver that is compatible with most microcontrollers and capable of producing a digital 0 to 5V pulse (0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). A 7V to 30V power supply is required for the module's motor. The digital interface is powered by an onboard voltage regulator that can be set to 5V or 3.3V. The A3967 is a full-featured microstepping motor driver with an integrated transistor. It is intended for use with bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capabilities of 30 V and 750 mA. The A3967 comes with a fixed off-time current regulator that can operate in slow, fast, or mixed current-decay modes. This current-decay control scheme produces less audible motor noise, higher step accuracy, and lower power dissipation. The transistor is essential to the A3967's simple implementation. Simply sending one pulse to the STEP input causes the motor to move one step (full, half, quarter, or eighth depending on two logic inputs). It is not necessary to programme phase-sequence tables, high-frequency control lines, or complex interfaces. The A3967 interface is ideal for applications where a complex P is either unavailable or overburdened. Features: A3967 microstepping driver Adjustable current control from 150mA/phase to 750mA/phase MS1 and MS2 pins are broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth) Compatible with 4, 6, and 8-wire stepper motors of any voltage Breadboard-compatible pins.

Cytron Maker Reflect IR Reflectance Sensor for Beginner The Cytron Maker Reflect IR Reflectance Sensor is a compact and beginner-friendly module designed to help learners understand how infrared reflectance works in robotics and automation. Using an IR LED and a high-sensitivity phototransistor, it measures how much IR light bounces back from a surface and generates an analog voltage that’s easy for any microcontroller to read. This makes it perfect for exploring concepts like surface detection, black-and-white line following, and reflectivity measurement. Designed by Cytron with simplicity in mind, this sensor is ideal for kids, students, and makers stepping into DIY robotics projects. Its ultra-small size and centered mounting hole allow it to fit even in tight robot designs, while its 3.3V and 5V compatibility ensures smooth use with Arduino, Raspberry Pi, and all common controllers. Whether you're building a line follower, Sumo bot, maze robot, or encoder-based mechanism, the Maker Reflect delivers reliable IR performance with minimal setup. Features: Works as a hands-on IR reflectance sensor that uses an IR LED + phototransistor to measure surface reflectivity for reliable detection. Helps beginners learn analog sensing, line detection, object presence, and robot navigation, building strong STEM fundamentals. Built with safe, durable Cytron components, ensuring stable performance even in beginner-level DIY robotics projects. Fully compatible with 3.3V and 5V systems, making it easy to interface with Arduino, Raspberry Pi, microcontrollers, and robotics platforms. Offers a sensing distance of 1mm to 40mm at 5V (ideal for black/white surface detection and line following). Provides analog voltage output, allowing smooth interpretation of different surface colors and reflectivity. Compact size of 18.1mm × 8.4mm × 4.2mm, with a centered mounting hole for accurate positioning at the front of robots. Suitable for school projects, robotics clubs, and maker experiments - perfect for line followers, Sumo robots, maze solvers, and encoder wheels.

DFRobot Gravity 7/24 Industrial Analog pH Sensor Meter Kit for Arduino The DFRobot Gravity 7/24 Industrial Analog pH Sensor Meter Kit for Arduino is a high-precision Analog pH Sensor designed for professional and industrial applications requiring continuous pH monitoring. This Arduino pH Sensor uses an industrial-grade glass membrane electrode with low impedance, delivering fast response, excellent thermal stability, and stable performance over long periods. It supports a full measurement range of 0 pH to 14 pH with linear voltage output, ensuring accurate and reliable readings. The sensor integrates easily through a BNC connector and PH2.0 interface, allowing direct connection to any Arduino analog input. Its reference system, based on Ag/AgCl gel electrolyte with a PTFE membrane, provides strong anti-pollution characteristics and prevents clogging, making it an ideal industrial pH sensor for Arduino for water treatment systems, environmental monitoring, and laboratory analysis. Attention: The probe's bottle top contains protective fluids (3.3mol/L KCL). Even if the bottle cap is tightly fastened, some protective liquid may leak around it, resulting in white crystals. However, as long as the bottle top contains protective liquid, the probe's life and accuracy will be unaffected. Please use it with confidence. It is recommended that the white crystals be returned to the bottle cap's protective liquid. Features Industrial-grade Analog pH Sensor for accurate measurement Compatible with Arduino and other microcontrollers Measures pH range from 0 to 14 Fast response with high stability BNC connector for secure sensor connection Plug-and-play PH2.0 analog interface Built-in power indicator LED Suitable for long-term online monitoring Low maintenance and long sensor life Ideal for water quality and lab applications Applications Water Quality Surveillance Aquaculture
