A4988 stepper motor driver board

Euro 2.50 *Prices include VAT

Article code: TOO120-H1

The A4988 driver is a commonly used bipolar stepper motor driver that can provide up to 2A current per coil from 8V to 35V. These drivers are used to drive NEMA 17 motors on the Mill One. This driver also allows for up to 16th microstepping.

Features:

1. Simple control interface and direction direction

2. Short-to-ground and short-load protection

3. Five different step decisions: full step, half step, quarter step, eighth step, and sixteenth step

4. intelligent chopping controller that automatically chooses the correct current decay mode (decay Fast or slow decay)

5. Over-temperature thermal shutdown, under voltage locking, and crossover-current protection

6. Adjustable current control allows you to set the maximum output current with voltage, which allows you to use voltages above the voltage of your stepper motors In voltage to achieve higher

Motors drive output power of up to 35V and ± 2A. A4988 includes constant outside time current regulator, regulator in modes Slow or mixed decay. A4988 convert is the key for ease of implementation. As long as the "step" inputs one pulse input drives one microstep motor. There are no phase sequence tables, high-frequency control lines, or complex program interfaces. A4988 interface is very suitable for unavailable or overburdened complex processors.

In a small step process, the A4988 cuts off the control inside automatically by determining the current decay mode (slow or mixed). In mixed decay mode, the device is initially set to a static stop in some rapid decay, then the rest of the stop time is slow to decay. Mixed decay current control system results in lower audible engine noise, increased step accuracy, and lower power consumption. Internal circuit monitoring synchronous correction is provided to improve pulse width modulation (PWM) process power consumption. Inner circuit protection includes: thermal shutdown with deceleration, undervoltage lockout (OFLO), and cross-current protection. Special power sequence.
