SparkFun ProDriver - Stepper Motor Driver (TC78H670FTG)

The SparkFun ProDriver is a powerful tool that enables you to work effortlessly with the TC78H670FTG bipolar stepper motor driver from Toshiba. Its latch terminals allow for quick, solder-less connections to all the features it offers. With the help of SparkFun's extensive Arduino Library, you can easily navigate through the diverse features of this compact motor driver IC.

The ProDriver offers high-resolution control, enabling you to manage operations down to 1/128th of a step. It can be controlled using traditional clock-in stepping or serial commands, as demonstrated in the Arduino Library. The serial command method stands out as it lets you control the phase, torque, current limit, and mixed decay ratio of each coil in real time during stepping. Unlike most stepper motor driver ICs that require an external trimpot to set the current limit, the ProDriver lets you adjust this precisely via serial commands.
