描述

SparkFun EasyDriver – A3967 Stepper Motor Driver 步進馬達驅動版 SparkFun 原裝進口

SparkFun EasyDriver – Stepper Motor Driver 是一款簡單易用的步進電機驅動器，與任何可以輸出數字0至5V脈衝（如果您在 EasyDriver 上關閉SJ2時輸出0至3.3V脈衝）兼容。EasyDriver需要一個6V至30V的電源為電機供電，並且可以為步進電機的任何電壓供電。EasyDriver具有用於數字接口的板上穩壓器，可以將其設置為5V或3.3V。連接一個4線步進電機和一個微控制器，你就有了精確的電機控制！EasyDriver驅動雙極電機，電機連接為雙極性。即4,6或8線步進電機。

EasyDriver V4.5與 Brian Schmalz共同設計。與舊版本相比，它提供更多的靈活性和對步進電機的控制。A3967 的微步選擇（MS1和MS2）引腳斷開，允許調整微步進分辨率。睡眠和使能引腳也被打破以進一步控制。

注意：驅動器通電時請勿連接或斷開電機。這會對A3967 IC造成永久性損壞。

• A3967微步進驅動器
• MS1和MS2引腳斷開，將微步分辨率更改為全步，半步，四分之一和八步（默認為第八步）
• 與任何電壓的4,6和8線步進電機兼容
• 從150mA /相到700mA /相的可調電流控制
• 電源範圍從6V到30V。電壓越高，高速時的轉矩越高。

EasyDriver – Stepper Motor Driver

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board 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 wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.

This EasyDriver V4.5 has been co-designed with Brian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.

Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.

Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.

• A3967 Microstepping Driver
• MS1 and MS2 pins 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
• Adjustable current control from 150mA/phase to 700mA/phase
• Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
