The SparkFun AutoDriver- Stepper Motor Driver ( v13 ) board is based on the STMicro L6470 dSPIN stepper motor driver. STMicro’s L6470 is a 3A, 8–45V bipolar stepper motor driver, it can be used to control a stepper motor with a voltage from 8 to 45V at 3 arms over an SPI connection. The Auto driver board has been designed to be easily integrated into a project, even with multiple boards.
STMicro’s L6470 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. It also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting.
The L6470 requires more configuration and adds software complexity to our system. The STMicro L6470 dSPIN stepper motor driver is controlled over an SPI link. It has an onboard 16MHz oscillator, which allows to autonomously execute movement commands. It also supports customized acceleration and deceleration profiles to prevent jerky starts and stops. Onboard registers track current speed and location.
The logic supply voltage supports both 3.3V and 5V I/O levels.
