These carrier boards for Allegro’s A4988 bipolar stepper motor driver feature adjustable current limiting, over-current and over-temperature protection, and five microstep resolutions (down to 1/16-step). They operate from 8 V to 35 V and can deliver approximately 1 A per phase without a heat sink (they are rated for up to 2 A per coil).

These Black Edition drivers are higher-performance drop-in replacements for the original A4988 stepper motor driver carrier. They feature a four-layer PCB for better thermal performance, allowing the A4988 microstepping bipolar stepper motor driver to deliver approximately 20% more current than our two-layer version.

These carrier boards for Allegro’s A5984 stepper motor drivers are great low-cost solutions for controlling bipolar stepper motors. They operate from 8 V to 40 V and can deliver up to 1.2 A continuous per phase (2 A peak). Fixed and adjustable current limit versions are available.

These boards are simple carriers of Allegro’s high-current ACS37220 Hall effect-based, electrically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing, an extra-low-resistance (~0.1 mΩ) current path, configurable overcurrent fault, and electrical isolation. 3.3.V and 5V versions are available.

These boards are simple carriers of Allegro’s ACS711 Hall effect-based, electrically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer a low-resistance (~0.6 mΩ) current path and electrical isolation up to 100 V.

These boards are simple carriers of Allegro’s ACS71240 Hall effect-based, electrically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing for higher accuracy, a low-resistance (~0.6 mΩ) current path, and electrical isolation. 3.3.V and 5V versions are available.

These boards are simple carriers of Allegro’s 5V ACS724 Hall effect-based, electrically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing for higher accuracy, a low-resistance (~0.6 mΩ) current path, and electrical isolation.

These boards are simple carriers of Allegro’s high-current ACS72981 Hall effect-based, electrically isolated current sensors, which output an analog voltage proportional to the current passing through them. They offer differential sensing, a low-resistance (~0.2 mΩ) current path, a high 250 kHz bandwidth, and electrical isolation. 3.3.V and 5V versions are available.

These boards are simple carriers of Allegro’s high-dV/dt, high bandwidth (1 MHz) CT432/CT433 tunneling magneto­resistance (TMR) current sensors, which output an analog voltage proportional to the current passing through them. They offer common-field mode rejection, a low-resistance (~1 mΩ) current path, overcurrent fault, and electrical isolation. 3.3.V and 5V versions are available.

Pololu item #: 2137
Brand: Pololu
Status: Active 
RoHS 3 compliant
Out of stock.
Quantity:

This compact breakout board makes it easy to use Allegro’s A4990 dual motor driver, which can control two bidirectional DC motors over a wide operating voltage range of 6 V to 32 V. It is capable of delivering a continuous 0.7 A to each motor channel, and onboard sense resistors enable the A4990 to limit the peak motor current to about 0.9 A per channel. The driver also features protection against reverse-voltage, under-voltage, over-voltage, over-current, and over-temperature.

Pololu item #: 2512
Brand: Pololu
Status: Active 
RoHS 3 compliant
Out of stock.
Quantity:

This small shield is an easy, economical way to control two small brushed DC motors with an Arduino or Arduino-compatible board. Its integrated A4990 dual motor driver operates from 6 V to 32 V and can deliver a continuous 0.65 A to each motor channel, making it a great control option for low-current motors that run on high voltages. The A4990 is configured to limit the peak motor current to about 0.9 A per channel and is protected against reverse-voltage, under-voltage, over-voltage, short-circuit, and over-temperature conditions.
