Product Description





Product features: 1, the subdivision is up to 256. 2, support SPI interface control; 3. When the high load is driven, the step will not be lost. 4, the logic interface level is: 3-5V; 5, the input voltage range: 4.75-46V DC; 6, two phase stepping motor single-phase current 1.2A (peak 2A) motor working current can be adjusted. 7. Spreadcycle ensures smooth transition of stepper motor at zero crossing point without dead zone current, and TMC2130 stepping motor drive chip has almost no jitter. 8, StealthChop can drive the motor to work under extreme mute, which can control the motor sound below 10dB decibels, and the noise is much lower than the traditional current control mode. 9, the SpreadCycle PWM chopper mode automatically configures a hysteresis attenuation function between the slow and fast attenuators, the average current reacts the normal current of the configuration, and there is no transition period in the zero crossing point of the sine, which reduces the fluctuation of current and torque, and makes the current waveform closer to the sine wave, compared with the traditional constant chopper mode. The SpreadCycle PWM chopper mode controlled the motor running smoothly and smoothly. Subdivision: Product pin definition: upper lower Driving current algorithm and regulation 1. Vref measure the voltage between the Gnd and the middle part of the potentiometer. 2, the voltage should be connected to the power supply, not only connected to USB power supply. 3, do not connect the motor when measuring the voltage, otherwise it will burn down the driver easily. 4, driving current algorithm: i=Vref*1.9/2.5, the default Vref is about 1V, so the default current is 0.76A, the maximum current is 2A! Please pay special attention to the direction, do not insert the reverse!
