USB Controller Board -Stepper Driver Highlights Generic Stepper Driver STMicros L6470 (aka dSPIN) is a 3A, 8-45V bipolar stepper motor Built-in detection / built-in undervoltage / detection overheat/shutdown, a 5-bit ADC and a switch input that can be used for user jog control or as a hard stop function Microstepping support (up to 128 microsteps per full step) and limit of PWM control voltage Ease the implementation of dSpin in your project. Just connect motors and pass-capable SPI microcontroller Support custom acceleration and deceleration profiles to prevent Jerky from starting and stopping Specification: Material: Electronic components Size: Approx. 47x38x12mm / 1.85x1.50x0.47inch Package includes: 1 Piece Stepper Driver Board Note: Colors may be different for the different display, please understand Please allow 1-3mm error due to manual measurement, please make sure sure you dont mind before bidding
