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-25167:1.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 SparkFun Mini Stepper Motor Driver empowers you to control bipolar stepper motors with ease and precision. This compact driver, measuring just 0.6in. by 0.8in. with breadboard-friendly 0.1in. pin spacing, shines in space-constrained projects and prototyping applications. Getting started is a breeze thanks to our comprehensive [Arduino Library](https://github.com/sparkfun/SparkFun_ProDriver_TC78H670FTG_Arduino_Library), which boasts 10 examples to guide you through the process. Furthermore, you achieve unmatched control over your motor's movement with high-resolution capabilities down to 1/128th of a step. The Mini Stepper Motor Driver offers two control methods for greater flexibility: traditional clock-in stepping and serial commands. The serial control method unlocks unique features, allowing you to fine-tune your motor's performance on the fly. Adjust phase, torque, current limit, and mixed decay ratio easily through user-friendly serial commands. Unlike most stepper motor driver ICs that require an external trimpot for current limit adjustments, the Mini Stepper Motor Driver empowers you with software-based control, eliminating the need for physical adjustments. [Get Started with the SparkFun ProDriver and Mini Stepper Motor Driver Hookup Guide](https://learn.sparkfun.com/tutorials/1200) **Note:** For a tool-less version of this motor driver, please check out our [ProDriver](https://core-electronics.com.au/sparkfun-prodriver-stepper-motor-driver-tc78h670ftg.html). However, it should be noted that there is a slight difference in the functionality of the `3V3` pin. The ProDriver only requires a single input power supply, as the `3V3` pin is a voltage output. ### Features - Toshiba TC78H670FTG Bipolar Stepping Motor Driver - Control Protocol: - Clock-in - Serial - Step operation: full, half, quarter, 1/8, 1/16, 1/32, 1/64, 1/128 - Power supply operating voltage: 3.6 V to 16.0 V - Output current: 2.0 A (max) - Over current protection from PTC - Multi error detect functions: - Thermal shutdown (TSD) - Over current (ISD) - Motor load open (OPD) - Under voltage lockout (UVLO) - Board Dimensions: 0.6in. × 0.8in. ### Documents - [Schematic](https://core-electronics.com.au/attachments/localcontent/schematic_5287838d4bc.pdf) - [KiCad Files](https://core-electronics.com.au/attachments/localcontent/kicad_files_22713c42d14.zip) - [Board Dimensions](https://core-electronics.com.au/attachments/localcontent/dimensions_34654f9b880.pdf) - [Hookup Guide](https://learn.sparkfun.com/tutorials/1200) - [Datasheet](https://core-electronics.com.au/attachments/localcontent/TC78H670FTG_datasheet_1488128f04d.pdf) (TC78H670FTG) - [Arduino Library](https://github.com/sparkfun/SparkFun_ProDriver_TC78H670FTG_Arduino_Library) - [GitHub Hardware Repo](https://github.com/sparkfun/SparkFun_Stepper_Motor_Carrier_TC78H670FTG) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/R/O/ROB-25167-1.jpg)
