A5984 Stepper Motor Driver Carrier, Adjustable Current, Blue Edition
This is a carrier board for Allegro’s A5984 microstepping bipolar stepper motor driver. It offers eight different microstep resolutions (down to 1/32-step) and has over-current and over-temperature protection, and it features an adaptive decay algorithm that automatically optimizes the motor current waveform. This version has an adjustable current limit that can be set with an on-board potentiometer and a four-layer PCB for better thermal performance, allowing it to deliver up to approximately 1.2 A continuous per phase without a heat sink or forced air flow (2 A peak).
Alternatives available with variations in these parameter(s): current limit header pins Select variant…
