L6470 Stepper Motor Driver Board

BOB-13752The SparkFun AutoDriver makes it easy to put the L6470 Stepper Driver (a.k.a dSPIN) to work in your project. Simply connect your motors and your SPI-capable microcontroller and get steppin’!
STMicros L6470 is a 3A, 8-45V bipolar stepper motor driver. It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function. As if that werent enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting.
Unlike most stepper motor drivers, the dSPIN is controlled over an SPI link. It has an on-board 16MHz oscillator which allows it to autonomously execute movement commands. That means no more counting steps in your code! It also supports customized acceleration and deceleration profiles to prevent jerky starts and stops. On-board registers track current speed and location.
The logic supply voltage supports both 3.3V and 5V I/O levels.
