Description: STMicro's L6470 (a.k.a "dSPIN") is a 3A, 8-45V bipolar stepper motor driver Built-in overcurrent/undervoltage/overtemperature/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 Microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting Make it easy to put the dSpin to work in your project. Simply connect motors and SPI-capable microcontroller and get stepping Support customized acceleration and deceleration profiles to prevent jerky starts and stops Specification: Material: Electronic components Size: Approx. 47x38x12mm/ 1.85x1.50x0.47inch Package Includes: 1 piece Stepper Driver Board Note: The colors may be different for the different display, please understand Please allow 1-3mm error due to manual measurement, make sure you do not mind before you bid
