The module is a driver for stepper motors.
The DRV8825 offers a micro activation of the bipolar stepper motor.
The module is provided with a particular pinout made to easily interface with the vector of the stepper motor A4988, so that it can be used as an improvement in several applications.
DRV8825 has overtemperature and overcurrent limiter and protection with adjustable current in six micro-resolution (pitch 1/32-step).
It Employs voltage from 8,2 to 45 V,and it is able to provide current up to 1,5 A on each phase without heatsink or forced air flow (rated up to 2,2A with external cooling system).
Six different resolutions: Full step, half step, 1/4-step, 1/8-step, 1/16-step, 1/32-step
CAN interface, direct interface with systems at 3,3 V and 5 V.
Thermal Shutdown: excessive temperature, overcurrent shutdown, undervoltage stoppage
Short circuit load protection
PCB with 2 copper plated layers, in order to improve the heat dissipation
The dimensions of the module, the pinouts and the interface match those of the A4988
Current control adjustable with a potentiometer, which allows to employ stepper motors at their rated voltage or even more, in order to reach an higher output rate with phase current
Intelligent control that automatically selects the mode or the precise decay (fast or slow)
Maximum supply voltage: 45V
Voltage regulator integrated (for each supply voltage of the external logic)
