A3967 Stepper Motor Driver Module
This EasyDriver compatible stepper motor driver module utilizes the Allegro A3967SLB micro-stepping driver to proved a simple and compact means of driving bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors from a microcontroller. By default, the module will accept a 5V TTL step and direction signal from the microcontroller to stop the motor in either full, half, quarter, and eighth-step modes. By shorting jumper SJ2 it can also be configured to be compatible with 3.3V microcontrollers that are not 5V tolerant. An onboard potentiometer allows for setting maximum drive current.

A3967 Stepper Motor Driver Module
- The A3967 Stepper Motor Easy Driver is a simple-to-use stepper motor driver, compatible with anything that can output a digital 0V to 5V pulse. (or 0V to 3.3V pulse if you solder SJ2 closed on the EasyDriver)
- EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of the stepper motor.
- The EasyDriver has an onboard voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors are wired as bi-polar. I.e. 4, 6, or 8 wire stepper motors.
- It provides much more flexibility and control over your stepper motor when compared to older versions. The microstrip select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the micro-stepping resolution. The sleep and enable pins are also broken out for further control. cjmcu made.
Features of A3967 Stepper Motor Easy Driver:
- MS1 and MS2 pins are broken out to change micro stepping resolution to full, half, quarter and eighth steps (defaults to eighth)
- Compatible with 4, 6, and 8-wire stepper motors of any voltage
- Adjustable current control from 150mA / phase to 750mA / phase
- Power supply ranges from 7V to 30V. The higher the voltage, the higher the torque at high speeds
- Distribution pin, not welded, this module is open-source

Arduino Starter Kit RFID Based
Arduino Starter Kit RFID Based walks you through the basics of using the Arduino & RFID in a hands-on way. You’ll learn through building several creative projects. The kit includes a selection of the most common and useful electronic components with a book of 15 projects. Starting from the basics of electronics to more complex projects, the kit will help you control the physical world with sensors and actuators.
This kit aims to bring Arduino together with RFID technology, which will support individual production. With this kit, you will be able to use RFID with the code you wrote in Arduino. You will be able to come up with a practical technology such as Arduino, a technology that many people like RFID are trying to get into and stay away from using. All of the components and components required for RFID technology are combined in this kit.
Radio Frequency Identification (RFID) is the given name to the technology used to identify objects using radio waves. An RFID microchip embedded in a tag, keychain or card communicates with the reader/writer module to transfer data.
