The SparkFun AutoDriver board is based on the STMicro L6470 dSPIN stepper motor driver. This powerful chip allows you to control a stepper motor with a voltage from 8 to 45V at 3Arms over an SPI connection. The AutoDriver board has been designed to be easily integrated into a project, even with multiple boards. Just connect your motors and your SPI-capable microcontroller and get steppin'.
STMicro's 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 weren't enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting. Please keep in mind that the L6470 requires a great deal more configuration and adds software complexity to your system.
FAQs:
Q: What are the key advantages of using the SparkFun AutoDriver compared to traditional stepper motor drivers?
A: The AutoDriver offers several advantages, including built-in microstepping, advanced current control, acceleration and deceleration profiles, and position tracking, all without requiring complex microcontroller code.
Q: What voltage and current range does the AutoDriver support for stepper motors?
A: The AutoDriver can handle motor supply voltages ranging from 8V to 45V and drive currents up to 3A per coil,making it suitable for various stepper motor sizes.
Q: How do I communicate with the AutoDriver from a microcontroller?
A: The AutoDriver uses an SPI interface to communicate with microcontrollers like Arduino, allowing for easy control and configuration of the motor driver.
Q: Can I daisy-chain multiple AutoDrivers together to control multiple motors?
A: Yes, the AutoDriver is designed for easy daisy-chaining, allowing you to control multiple motors with a single microcontroller using minimal wiring.
Q: Where can I find documentation, tutorials, and example code for the AutoDriver?
A: You can find comprehensive documentation, tutorials, and example code on the SparkFun website (https://learn.sparkfun.com/tutorials/getting-started-with-the-autodriver---v13/introduction) and GitHub repository (https://github.com/sparkfun/SparkFun_AutoDriver_Arduino_Library).
