The SparkFun Mini Stepper Motor Driver empowers you to control bipolar stepper motors with ease and precision. This compact driver, measuring just 1.5 cm by 2 cm with breadboard-friendly 2.54 mm pin spacing, shines in space-constrained projects and prototyping applications. Getting started is a breeze thanks to the comprehensive 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.Note: For a tool-less version of this motor driver, please check out the ProDriver. 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.Get Started with the ProDriver and Mini Stepper Motor Driver GuideFeatures: * 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: 1.5 cm × 2 cm Documents: * Schematic * KiCad Files * Board Dimensions * Hookup Guide * Datasheet (TC78H670FTG) * Arduino Library * GitHub Hardware Repo Videos https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-01-24 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-09-28 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-10-31 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-11-02 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-11-12 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-11-22 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-11-30 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-12-03 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-12-05 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2025-12-19 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-01-09 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-01-23 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-01-28 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-01-31 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-02-05 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-02-11 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-02-13 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-03-05 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-03-15 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-03-22 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-04-13 https://elecena.pl/product/27751518/sparkfun-mini-stepper-motor-driver-tc78h670ftg 2026-04-15
