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. ## Pricing - **Price:** $30.70 (inc GST) — $27.91 AUD, exc GST - **Quantity discounts:** 5+ $27.07 (exc GST) · 25+ $26.51 (exc GST) · 100+ $25.40 (exc GST) ## Availability & dispatch - Available with a lead time — expect dispatch between Aug 31 and Sep 04. ## How to buy - **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ROB-12779:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ROB-12779:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description 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 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. Features: - 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 Documents: - [Schematic](https://core-electronics.com.au/attachments/localcontent/EasyDriver_v45_99194916573.pdf) - [Eagle Files](https://core-electronics.com.au/attachments/localcontent/EasyDriver_v45_99194916573.pdf) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/A3967-Datasheet_44550b9d44d.pdf) (A3967) - EasyDriver Website - Example Arduino Tutorial in Portuguese - Bildr Tutorial ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/r/o/rob-12779.jpg)
